PROSPECTUS SUMMARY

	The following summary is qualified in its entirety by the more detailed 
information and financial statements appearing elsewhere in this Prospectus 
and in documents incorporated herein by reference.

About Sheldahl

	Sheldahl is a leading producer of high quality flexible printed 
circuitry and laminate materials, principally for sale to the automotive 
electronics and data communication markets.  Flexible circuitry is used to 
provide electrical connection between components and electronic systems and 
also as a substrate to support electronic devices.  Flexible circuits consist 
of polyester or polyimide film to which copper is adhered to and processed 
through various imaging, etching and plating processes.  Flexible circuits 
can be further processed by surface mount attachment of electronic components 
to produce an interconnect assembly.  Flexible circuits provide advantages 
over rigid printed circuit boards by accommodating packaging contour and 
motion and reducing size and weight.  

	In 1994, Sheldahl began to invest and extend its manufacturing process 
capabilities towards the production of flexible circuits that offer greater 
circuitry density.  This product line utilized our patented Novaclad material 
and we are marketing it to integrated circuit (IC) OEM and package 
assemblers.  We created the Micro Products business to market and sell this 
Novaclad-based material under the trade names ViaThin and ViaArray targeted 
for use in ball grid array (BGA) IC packages.  Production for these products 
originates in our Longmont, Colorado facility. 

	Sheldahl was incorporated in 1955 under the laws of the State of 
Minnesota.  Our principal executive offices are located at 1150 Sheldahl 
Road, Northfield, Minnesota 55057 and our telephone number is (507) 883-6000.

The Offering

	The selling shareholders are offering 1,592,160 shares of common stock.  
These shares are issuable upon conversion of shares of Series E convertible 
preferred stock and upon exercise of warrants issued by Sheldahl in a private 
placement on February 26, 1999 and when issued will represent 12.49% of our 
outstanding common stock.

stock.  See "Use of Proceeds."

Risk Factors

	This offering involves certain investment risks.  See "Risk Factors."

RISK FACTORS

	You should carefully consider the following risks before making an 
investment decision.  The risks described below are not the only ones that we 
face.  Our business, operating results or financial condition could be 
materially adversely affected by any of the following risks.  The trading 
price of our common stock could decline due to any of these risks, and you 
may lose all or part of your investment. You should also refer to the other 
information included or incorporated by reference in this prospectus, 
including our financial statements and related notes. 

Our Cash Flow is Minimal and We May Need Additional Financing
_______________

	We anticipate, although there can be no assurance, that continued 
improved performance of  our existing Interconnect and Materials business in 
our Northfield, Minnesota facilities, along with reduced capital spending, a 
strengthened balance sheet from the proceeds of the Series E Preferred Stock 
and our existing credit facility will provide adequate liquidity to fund 
operations.  If our Interconnect and Materials business in Northfield do not 
continue to improve, or if anticipated sales revenue from Micro Products is 
not achieved by the first quarter of fiscal 2000, our liquidity position 
would significantly deteriorate so that existing debt capacity would be 
reduced to minimal levels within twelve months.  Therefore, if we do not 
achieve our projected operating results, or if we do not have borrowings 
available under our current credit and security agreement, we believe that we 
would have to seek other options such as issuing additional new debt or 
additional new equity financing.  There can be no assurance, however, that we 
will be able to issue any debt successfully or raise capital on terms 
acceptable to us. 

	We have dedicated approximately $4.6 million of our expected cash flow 
to fund restructuring charges taken over the last twelve months to pay for 
employee separation costs, thereby negatively impacting our cash flow.  
During the second half of fiscal 1999, we are projecting sales levels to 
increase as our Longmont facility, the principal manufacturing site for our 
Micro Products business, generates greater sales volume resulting in funds to 
cover an increasing portion of fixed costs and improve cash flow thus 
reducing the growth in our debt financing.  We can not give assurance, 
however, that we will achieve projected sales levels during the second half 
of fiscal 1999 and into fiscal 2000. 

Our Operations Depend on the Acceptance of Our New Micro Products By the Data 
Communications Market IC Packaging Segment
_______________

	Sheldahl's future operating results and growth in net sales depend 
significantly upon the anticipated data communication market IC packaging 
segment's acceptance of Novaclad-based ViaArray and ViaThin products which 
our Micro Products business markets.  Although we believe that these products 
have attractive performance characteristics as well as utility in a 
potentially broad range of products, their sales will depend on our ability 
to:

- -	convince potential customers that the advantages and applications 
of the products justify the expense and production changes necessary to 
incorporate them into the customer's manufacturing process;

- -	work with designers of integrated circuit ("IC") packages and 
electronics to incorporate the products;

- -	qualify our products within the customer's design cycle time 
requirements so that the customer can include them within their 
products;

- -	produce sufficient quantities of the product at industry quality 
standards and deliver to customers in a timely manner.
	
As we have experienced in the past, any failure or significant delay in 
qualifying, producing, marketing and selling these products could have a 
material adverse effect on our business and financial performance until we 
achieve efficient volume production and related sales revenue.

Delay in the Utilization of Our Longmont Facility Continues to Adversely 
Impact our Financial Condition
_______________

	During the first six months of fiscal 1999, the Micro Products business 
resulted in a pretax loss prior to restructuring charges of $9.2 million.  We 
have experienced and will continue to experience a significant adverse 
financial impact with respect to developing the Micro Products business.  In 
1998, the Micro Products business resulted in a pretax loss prior to 
restructuring costs and impairment charges of $19.4 million as compared with 
a $15.5 million and $6.0 million loss in 1997 and 1996, respectively.  We 
expect such significant losses to continue until Longmont achieves efficient 
volume production and related sales revenue results.  As of February 26, 
1999, Longmont is operating at less than 10% of stated production capacity 
with projected breakeven gross margin at 45% of factory utilization, or some 
$24 million to $26 million of annual revenue of ViaThin and ViaArray 
products.  We do not expect breakeven volume at Longmont until the first 
quarter of fiscal 2000 at the earliest, and the fourth quarter of fiscal 2000 
at the latest.  Investors should be aware that validation problems or other 
difficulties may materialize once full volume production has commenced, and 
we may not be able to achieve breakeven production in the time specified, or 
at any time.

	As of the date of this prospectus, Texas Instruments and Vitesse 
Semiconductor have qualified ViaThin substrates for their operations.  We 
have begun shipping small volume production orders to these customers, and we 
expect that their initial orders will lead to larger orders from these and 
other customers as demonstrated by new designs and prototype orders currently 
in process from these and other customers.  We can give no assurance, 
however, that such future orders will occur.

We Depend Significantly on the Automotive Market
_______________

	Our sales to the automotive market as a percentage of our total sales 
were approximately 67.5% in fiscal 1997, 68.7% in fiscal 1998 and 68.7% for 
the first half of fiscal 1999.  In addition, our customer base is 
concentrated with our ten largest customers for fiscal 1998 accounting for 
approximately 64.1% of our net sales.  During fiscal 1998, 15.4% of our net 
sales were to Motorola, Inc., 10.2% were to Ford Motor Company and 10.3% were 
to Siemens, essentially all for automotive end-use applications.  We expect 
that for the foreseeable future, sales to a relatively small number of 
customers will continue to account for a significant portion of our 
automotive sales.  Therefore, the loss of, or a significant decline in orders 
from, one or more of our key customers could have a material adverse effect 
on our business, results of operations and financial condition.  As a result, 
our business is directly dependent upon the conditions in the automotive 
industry and fluctuates as automotive manufacturers begin production of new 
models and end production of others.  Accordingly, any decrease in the number 
of the Company's electronic components included in new models could have a 
material adverse effect on our results of operations.  For example, during 
the fourth quarter of fiscal 1998, our sales to the automotive market were 
adversely impacted by the General Motors strike by approximately $2.0 
million.  In addition, as the automotive industry continues to reduce the 
number of qualified suppliers and demand higher performance products at a 
lower cost, we can not be certain that we will be able to maintain our 
current sales volumes at existing profit margins to automotive manufacturers 
and their suppliers.

Rapid Technological Change Could Render Our Products Obsolete
_______________

	We supply the majority of  component products to customers in the 
automotive electronic and data communication markets which are characterized 
by rapid technological change and new product introductions and enhancements.  
Our future success in these markets will depend upon our ability to:

- -	work closely with manufacturers to design end products or 
applications which incorporate our products and achieve market 
acceptance;

- -	develop technologies to meet the evolving market requirements of 
our customers;

- -	continue to deliver high-performance, cost-effective products; 
and expand our sales and marketing efforts domestically and internationally.
	
We can give no assurance, therefore, that we will continue to meet the 
current qualification requirements of our major customers, meet the new 
qualification requirements imposed by our customers or continue to be 
selected as a supplier by new customers.

Our Business Requires Us to Make Significant Capital Expenditures Which We 
May Not Recover
_______________


	Our business is capital intensive.  For example, in the past four and a 
half years, we have invested approximately $116 million in total capital 
expenditures, including $66 million in our Longmont facility.  To remain 
competitive, we must continue to make significant expenditures for capital 
equipment, expansion of operations and research and development.  Although we 
have had some initial success introducing our Novaclad-based products, 
further penetration is required.  In order to accomplish such, we may need to 
make additional capital investments to increase manufacturing capacity before 
deriving sufficient positive cash flow from our initial investment in the 
Longmont facility.  Presently, capital expenditure plans in fiscal 1999 are 
planned at $7 million, significantly lower than in the recent past.  Reduced 
capital spending, along with anticipated improving cash flow from operations, 
funds available under our credit and security agreement, and proceeds from 
the sale of the Series E preferred stock are expected to provide adequate 
funds to meet our capital needs. There can be no assurance, however, that we 
will have adequate funds to support our capital expenditure plans beyond 
fiscal 1999. 

We Rely on Patents, Trademarks and Proprietary Rights to Protect Our Products
_______________

	We are aware of a patent which may cover certain plated through holes 
of double-sided circuits made of our Novaclad material.  Currently, the 
holder has not made any claims against us under this patent.  However, the 
patent owner may attempt to construe the patent broadly enough to cover our 
current or future manufacture of Novaclad-based products. We believe that 
prior commercial art and conventional technology, including certain Company 
patents exist which would allow us to prevail in the event any such claim is 
made under this patent.  Any action commenced by or against Sheldahl could be 
time consuming and expensive and could result in requiring us to enter into a 
license agreement or cease manufacture of any products ultimately determined 
to infringe such patent.  

Certain Anti-Takeover Provisions May Discourage Transactions In Our Stock
_______________

	The Company's Articles of Incorporation and the Minnesota Business 
Corporation Act include certain "anti-takeover" provisions.  These 
provisions, including the power to issue additional stock and to establish 
separate classes or series of stock, may, in certain circumstances, deter or 
discourage takeover attempts and other changes in control of the Company not 
approved by the Board. 

	In June of 1996, the Sheldahl Board of Directors adopted a Rights 
Agreement commonly called a poison pill.  According to the terms of the 
Rights Agreement, we issued one right in respect of each share of our common 
stock outstanding.  Such rights also attach to each share of common stock 
issued subsequent to the adoption of the Rights Agreement, including the 
shares offered.  Each right entitles the holder to purchase a fraction of a 
share of our Series A Preferred Stock or, in certain instances, our common 
stock or the stock of a third party or group (an "acquiring person") in the 
event that (i) an acquiring person acquires beneficial ownership of 15% or 
more of the common stock or (ii) a tender offer or exchange offer that would 
result in a person or group becoming an acquiring person is commenced. 

	 On July 30, 1998, we amended Section 1(a) of the Rights Agreement to 
provide that when applied to Molex Incorporated and any of its affiliated 
parties the 15% threshold for beneficial ownership shall be 22%.  We 
increased this threshold with respect to Molex in connection with Molex's 
investment in our Series D Preferred Stock private placement of July 1998 
which otherwise would have resulted in Molex triggering provisions of the 
Rights Agreement.  The Rights Agreement remains in effect through June 2006 
and could discourage tender offers or other transactions which could result 
in our shareholders receiving a premium over the market price of common 
stock.

	This Prospectus contains and incorporates by reference certain 
forward-looking statements based on current expectations which involve risks 
and uncertainties.  Actual results and the timing of certain events may 
differ materially from those projected in such forward-looking statements due 
to a number of risk factors, including those set forth below.  The Company 
has tried, wherever possible, to identify these forward-looking statements by 
using words such as "believe," "anticipate," "estimate," "expect" and 
similar expressions.  The Company undertakes no obligation to release 
publicly the results of any revisions to any such forward-looking statements 
that may be made to reflect events or circumstances after the date of this 
Prospectus or to reflect the occurrence of unanticipated events.

THE COMPANY

	See "Risk Factors" for information prospective investors should 
consider.  Novaclad(R), Novaflex(R), ViaThin(TM), ViaArray(R), and 
Novaflex(R) VHD are registered trademarks of the Company.

	Sheldahl is a leading producer of high quality flexible printed 
circuitry and laminate materials, principally for sale to the automotive 
electronics and data communication markets.  Flexible circuitry is used to 
provide electrical connection between components and electronic systems and 
also as a substrate to support electronic devices.  Flexible circuits consist 
of polyester or polyimide film to which copper foil is laminated and 
processed through various imaging, etching and plating processes.  Flexible 
circuits can be further processed by surface mount attachment of electronic 
components to produce an interconnect assembly.  Flexible circuits provide 
advantages over rigid printed circuit boards by accommodating packaging 
contour and motion and reducing size and weight.  

	Over the past four and a half years, we have introduced high 
performance products based on proprietary thin film laminate technology: 
ViaArray and ViaThin (high-density substrates).  ViaArray, a higher-value 
form of Novaclad, has predrilled small holes (vias) that allow printed 
circuit manufacturers to produce interconnects to meet the changing need of 
the market.  We use ViaArray to manufacture chip-carrier substrates (ViaThin) 
primarily for IC packages.  These Novaclad-based products provide substantial 
benefits compared to traditional flexible circuits and IC substrates, 
including the capability for very fine circuit traces (down to 1 mil, or .001 
inch) as well as greater heat tolerance and dissipation.  We designed these 
products to enable IC manufacturers to package future generations of ICs 
economically by attaching the silicon die to ViaThin or high-density 
substrates manufactured by other circuitry manufacturers using our Novaclad 
or ViaArray products.  As ICs are becoming increasingly powerful, they 
produce more heat and require a greater number of connections to attach the 
silicon die, placing substantially greater demands on IC packaging materials.  
These products support the industry's drive for increasing functional 
performance at a decreasing cost per function.  Additionally, Novaclad is 
used to manufacture our Novaflex VHD and Novaclad HD product lines.  Novaclad 
and Novaclad-based products accounted for $25.2 million or 21.5% of our net 
sales in fiscal 1998.

	Through February 26, 1999, we have invested approximately $66 million 
in an advanced new production facility in Longmont, Colorado to produce 
ViaArray and ViaThin products in commercial volumes.  As of November 1995, we 
anticipated investing approximately $38 million in the Longmont Facility.  
Changes in the product characteristics of high density substrates relating to 
precious metal plating, solder mask overcoat and testing, plus the 
installation of assembly equipment not originally anticipated, significantly 
increased the original investment to bring the Longmont Facility on line.  
Recent purchases of land and equipment needed to increase originally 
anticipated capacity also contributed to the total investment in the Longmont 
Facility.

	We originally expected to commence production in our Longmont facility 
in April 1996.  However, due to its own financial difficulties, one of our 
suppliers, Micro Plating Systems, Inc., delivered certain production 
equipment much later than initially scheduled and subsequently exceeded our 
anticipated installation period.   In order to improve the design and 
delivery of future key production equipment, we have identified additional 
equipment suppliers.  In addition to equipment problems, a more rigorous and 
lengthy process qualification and product acceptance by our customers as well 
as our customer's customers further delayed the facility's realization of 
full volume production.  As of the date hereof, however, Texas Instruments 
and Vitesse Semiconductor have qualified ViaThin substrates for their 
operations.  We have begun shipping small volume production orders to these 
customers, and we expect that their initial orders will lead to larger orders 
from these and other customers as demonstrated by new designs and prototype 
orders currently in process from these and other customers.  As of February 
26, 1999, the Longmont Facility is operating at less than 10% of stated 
production capacity with projected breakeven at 45% of factory utilization or 
some $24 million to $26 million of annual revenue of ViaThin and ViaArray 
products.  Breakeven volume at Longmont is not expected until the first 
quarter of fiscal 2000 at the earliest, and the fourth quarter of fiscal 2000 
at the latest.  


YEAR 2000 ISSUES

	Year 2000 Disclosure.  	The Year 2000 issue is the result of computer 
programs being written using two digits rather than four to define the 
applicable year. Our computer equipment, software, devices and products with 
imbedded technology that are time-sensitive may recognize a date using "00" 
as the year 1900 rather than the year 2000. This could result in a system 
failure or miscalculations causing disruptions of operations, including, 
among other things, a shut down in our manufacturing operations, a temporary 
inability to process transactions, send invoices or engage in similar normal 
business activities.

	State of Readiness.  We have undertaken various initiatives to evaluate 
the Year 2000 readiness of our the products, the information technology 
systems we use in operations ("IT Systems"), our non-IT systems, such as 
power to its facilities, HVAC systems, building security, voicemail and other 
systems, as well as the readiness of our customers and suppliers.  We have 
identified eleven Year 2000 target areas that cover the entire scope of our 
business and have internally established teams committed to completing an 8-
step Compliance Validation Process ("CVP") for each target area.  Each team 
is expected to fully complete this process on or before September 1, 1999.  
The table below identifies our target areas as well as the 8-step CVP with 
our expected timeline.  Sheldahl's Y2K teams are either complete or near 
complete with Phase 1 of this process and progressing with Phase 2 
remediation activities.

4. Sign-Off Acceptance

	With respect to our relationships with third parties, we rely both 
domestically and internationally upon various vendors, governmental agencies, 
utility companies, telecommunications service companies, delivery service 
companies and other service providers. Although these service providers are 
outside our control, we have has mailed letters to those with whom we believe 
our relationships are material and have verbally communicated with some of 
our strategic customers to determine the extent to which interfaces with such 
entities are vulnerable to Year 2000 issues and whether products and services 
purchased from or by such entities are Year 2000 ready.  In February 1999 we 
initiated a Business Partner Assessment Program focused on evaluating 
customers and suppliers Year 2000 readiness to identify third parties that 
imposed significant risk on Sheldahl.  We intend to complete follow-up 
activities, including but not limited to site surveys, phone surveys, 
mailings and remediation assistance, with identified third parties as part of 
the Phase 2 validation.  
 
	Costs to Address Year 2000 Issues.  To date, the we have not incurred 
any material expenditures in connection with identifying or evaluating Year 
2000 compliance issues.  We have incurred the majority of our costs from the 
recent installation of a business computer system consisting primarily of the 
Enterprise Requirements Planning (ERP) System as well as the opportunity cost 
of time spent by our employees evaluating Year 2000 compliance matters 
generally.  Because we did not accelerate the installation of the ERP System, 
we do not consider the costs related thereto to be charges for Year 2000 
compliance.  Presently, we estimate the cost of Year 2000 upgrades and 
enhancements to our IT Systems and non-IT Systems to be less than $100,000. 
We anticipate that these costs will be contained within our fiscal 1999 
budget.  At this time, we do not possess information necessary to estimate 
the potential financial impact of Year 2000 compliance issues relating to our 
vendors, customers and other third parties.  Such impact, including the 
effect of a Year 2000 business disruption, could have a material adverse 
impact on our financial condition and results of operations. 

	Risks of Year 2000 Issues.  Because we are still in the discovery and 
evaluation phase of assessing our overall Year 2000 exposure, we cannot at 
this time state with certainty that the Year 2000 issues will not have a 
material adverse impact on our financial condition, results of operations and 
liquidity.  Although we consider them unlikely, we believe that the following 
several situations, not in any particular order, make up our "most 
reasonably likely worst case Year 2000 scenarios":  

	1.  Disruption of a Significant Customer's Ability to Accept Products 
or Pay Invoices. 

Our significant customers are large, well-informed customers, mostly in 
the automotive field, who are disclosing information to their vendors 
that indicates they are well along the path toward Year 2000 
compliance.  These customers have demonstrated their awareness of the 
Year 2000 issue by issuing requirements of their suppliers and 
indicating the stages of identification and remediation which they 
consider adequate for progressive calendar quarters leading up to the 
century mark.  Our significant customers, moreover, are substantial 
companies that we believe would be able to make adjustments in their 
processes as required to cause timely payment of invoices.  Because of 
lengthy lead times in the industry, disruption of orders from Sheldahl 
is not likely a problem.  Any deliveries occurring in the first half of 
2000 will be those resulting from orders placed in 1999, while any 
disruptions of the order process early in 2000 will concern deliveries 
made many months later, with adequate opportunity for correction (or 
manual handling) of the order process before the timing becomes 
critical.

	2.  Disruption of Supply Materials.  

Recently, we began a process of surveying our vendors for public 
disclosures in regards to their Year 2000 readiness and are now in the 
process of assessing and cataloging these disclosures. We expect to 
work with vendors that provide inadequate disclosures or show a need 
for remediation assistance.  Where ultimate survey results show that 
the need arises, we will arrange for back-up vendors before the 
changeover date.

	3.  Disruption of the Company's IT Systems.  

We are proceeding with a scheduled upgrade of our current hardware and 
software IT systems to state-of-the-art systems and such process has 
required Year 2000 compliance in the various invitations for proposals.  
Year 2000 testing is occurring as upgrades proceed and, in addition, 
will occur after all upgrades are complete, sometime during fiscal 
1999.  For this reason, we consider that disruption of our IT Systems 
is unlikely. 

	4.  Disruption of the Company's Non-IT Systems.  

We are completing a comprehensive assessment of all non-IT systems, 
including among other things our manufacturing systems and operations, 
with respect to both embedded processors and obvious computer control.  
For some systems, upgrades are already completed or scheduled, and the 
remaining non-compliant systems remediation needs are being planned.  
Considering the nature of the equipment and systems involved, we expect 
to complete any remediation efforts on a reasonably short schedule, and 
in any case before arrival of the Year 2000.  We also believe that, 
after such assessment and remediation, if any disruptions do occur, 
such will be dealt with promptly and will be no more severe with 
respect to correction or impact than would be an unexpected breakdown 
of well-maintained equipment.

	5.  De-Listing of Company as a Vendor to Certain Customers.  

Several of our principal customers, through the intermediary of an 
automotive industry information agency, have required updated reports 
in the form of answers to an extensive multiple-choice survey on our 
Year 2000 compliance efforts.  According to these customers, failure to 
reply to the readiness survey would have led to de-listing as a 
supplier at the present time, resulting in possible current inability 
to bid on procurements requiring deliveries two years or more in the 
future.  Although we did respond to these reports on a timely basis, 
the substance of our answers to the readiness surveys have placed 
Sheldahl in a "red" or "danger" zone with respect to those 
customers' guidelines.  One of our two largest customers involved in 
the efforts of the independent audit agency had also already presented 
a survey directly to Sheldahl, and as a result had arranged at its own 
expense for an independent audit of our Year 2000 readiness.  The 
independent audit agency had reported, in the third quarter of fiscal 
1998, that although Sheldahl's level of readiness placed us in the 
"red" or "danger" category, we (i) were proceeding rapidly with its 
evaluation and remediation efforts, (ii) were expected to reach the 
ultimate compliance goals of the survey in adequate time, and (iii) 
should not be considered a risk to the customer's sources of supply. In 
December 1998, Sheldahl was re-audited by a Remediation Assistance 
Program consultant on behalf of this customer.  At the conclusion of 
this audit the consultant recommended that Sheldahl's Year 2000 
Readiness be upgraded to a "medium level of risk" from the previous 
high level of risk ("red zone").  Furthermore, the consultant noted 
that in reviewing Sheldahl's "Y2K plan against the goals of the 
remediation assistance process, the assessor could not find any gaps or 
areas of recovery that were not covered or considered."  We expect but 
cannot guarantee that responses from other customers will be similar.  
In addition, we do not know whether other customers' expectations will 
or will not be as stringent as those referred to above and whether our 
current schedule will meet or exceed such expectations. 

	Contingency Plans.  While we recognize the need for contingency 
planning, we have not yet developed any specific contingency plans for 
potential Year 2000 disruptions.  The aforementioned 8-step Compliance 
Validation Process, however, does include contingency planning by each team 
and we will review such plans as developed.  We do anticipate developing 
contingency plans for our most critical areas, but details of such plans will 
depend on our final assessment of the problem as well as the evaluation and 
success of our remediation efforts.  Future disclosures will include 
contingency plans as they become available.

USE OF PROCEEDS

	We will not receive any proceeds from the sale of the shares offered in 
this prospectus by the selling shareholders.  With respect to the proceeds 
from the private placement of the Series E shares, see "Recent Developments 
- -- Series E Preferred Stock; Use of Proceeds."  If the warrants are 
exercised in full, we will receive $668,750.  We intend to use such amount 
for working capital purposes. We can give no assurance, however, that 
investors will exercise any of the warrants.

SELLING SHAREHOLDERS

	The shares of common stock offered in this prospectus by the selling 
shareholders are issuable (i) upon conversion of the Series E preferred stock 
held by the selling shareholders, (ii) as accrued dividends on the Series E 
preferred stock and (iii) upon the exercise of outstanding warrants held by 
the selling shareholders.  A total of 8,560 shares of Series E preferred 
stock and warrants to purchase up to 85,600 shares of our common stock at an 
exercise price of $7.8125 per share were issued to the selling shareholders 
in connection with a private placement in February 1999.  Through April 8, 
1999, no shares of the Series E preferred stock have been converted.

	The amount of common stock shown in the following table represents the 
amount into which the 8,560 shares of Series E preferred stock might have 
been converted on April 8, 1999 based on the conversion price of $6.25.  The 
amount of common stock shown in the table also includes 136,960 shares of 
common stock representing accrued dividends for two years on the shares of 
Series E preferred stock based on the $6.25 conversion price, as well as 
85,600 shares of common stock issuable to the selling shareholders upon 
exercise of the warrants:

EXPERTS

in this registration statement have been audited by Arthur Andersen LLP, 
independent public accountants, as indicated in their reports with respect 
thereto, and are incorporated herein in reliance upon the authority of said 
firm as experts in accounting and auditing in giving said reports.


INDEMNIFICATION

	Sheldahl's Articles of Incorporation eliminate or limit certain 
liabilities of its directors and our Bylaws provide for indemnification of 
directors, officers and employees of Sheldahl in certain instances.  Insofar 
as exculpation of, or indemnification for, liabilities arising under the 
Securities Act of 1933 may be permitted to directors, officers or persons 
controlling Sheldahl pursuant to the foregoing provisions, Sheldahl has been 
informed that in the opinion of the Securities and Exchange Commission such 
exculpation or indemnification is against public policy as expressed in the 
Act and is therefore unenforceable.

ITEM 15:  Indemnification of Directors and Officers

	Section 302A.521 of Minnesota Statutes requires the Registrant to 
indemnify a person made or threatened to be made a party to a proceeding by 
reason of the former or present official capacity of the person with respect 
to the Registrant, against judgments, penalties, fines, including reasonable 
expenses, if such person (1) has not been indemnified by another organization 
or employee benefit plan for the same judgments, penalties, fines, including, 
without limitation, excise taxes assessed against the person with respect to 
an employee benefit plan, settlements, and reasonable expenses, including 
attorneys' fees and disbursements, incurred by the person in connection with 
the proceeding with respect to the same acts or omissions; (2) acted in good 
faith; (3) received no improper personal benefit, and statutory procedure has 
been followed in the case of any conflict of interest by a director; (4) in 
the case of a criminal proceeding, had no reasonable cause to believe the 
conduct was unlawful; and (5) in the case of acts or omissions occurring in 
the person's performance in the official capacity of director or, for a 
person not a director, in the official capacity of officer, committee member 
or employee, reasonably believed that the conduct was in the best interests 
of the Registrant, or, in the case of performance by a director, officer or 
employee of the Registrant as a director, officer, partner, trustee, employee 
or agent of another organization or employee benefit plan, reasonably 
believed that the conduct was not opposed to the best interests of the 
Registrant.  In addition, Section 302A.521, subd. 3, requires payment by the 
Registrant, upon written request, of reasonable expenses in advance of final 
disposition in certain instances.  A decision as to required indemnification 
is made by a disinterested majority of the Board of Directors present at a 
meeting at which a disinterested quorum is present, or by a designated 
committee of the Board, by special legal counsel, by the shareholders or by a 
court.  The Registrant's Bylaws provide for indemnification of officers, 
directors and employees to the fullest extent provided by Section 302A.521.

	As permitted by Section 302A.251 of the Minnesota Business Corporation 
Act, the Amended and Restated Articles of Incorporation of the Registrant 
eliminate the liability of the directors of the Registrant for monetary 
damages arising from any breach of fiduciary duties as a member of the 
Registrant's Board of Directors (except as expressly prohibited by Minnesota 
Statutes, Section 302A.251, subd. 4).

	Insofar as indemnification for liabilities arising under the Securities 
Act of 1933, as amended (the "Securities Act") may be permitted to 
directors, officers and controlling persons of the Registrant pursuant to the 
provisions referenced in Item 15 of this Registration Statement or otherwise, 
the Registrant has been advised that in the opinion of the Securities and 
Exchange Commission such indemnification is against public policy as 
expressed in the Securities Act, and is, therefore, unenforceable.  In the 
event that a claim for indemnification against such liabilities (other than 
the payment by the Registrant of expenses incurred or paid by a director, 
officer or controlling person of the Registrant in the successful defense of 
any action, suit or proceeding) is asserted by such director, officer or 
controlling person in connection with the securities being registered 
hereunder, the Registrant will, unless in the opinion of its counsel the 
matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnification by it is 
against public policy as expressed in the Securities Act and will be governed 
by the final adjudication of such issue.

	In addition, the Registration Rights Agreement, filed as an Exhibit

Item 17.  Undertakings

	The undersigned Registrant hereby undertakes, in accordance with Item 
512 of Regulation S-K:

(a)	(1)	To file, during any period in which offers or sales are being 
made, a post-effective amendment to this Registration Statement to include 
any material information with respect to the plan of distribution not 
previously disclosed in the Registration Statement or any material change to 
such information in the Registration Statement;

	(2)	That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be deemed to 
be a new registration statement relating to the securities offered therein, 
and the offering of such securities at that time shall be deemed to be the 
initial bona fide offering thereof;

	(3)	To remove from registration by means of a post-effective 
amendment any of the securities being registered which remain unsold at the 
termination of the offering;

	(b)	That, for purposes of determining any liability under the 
Securities Act of 1933, each filing of the Registrant's annual report 
pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 
that is incorporated by reference in the Registration Statement shall be 
deemed to be a new registration statement relating to the securities offered 
therein, and the offering of such securities at that time shall be deemed to 
be the initial bona fide offering thereof; and

	(e)	To deliver or cause to be delivered with the Prospectus, to 
each person to whom the Prospectus is sent or given, the latest annual report 
to security holders that is incorporated by reference in the Prospectus and 
furnished pursuant to and meeting the requirements of Rule 14a-3 and Rule 
14c-3 under the Securities Exchange Act of 1934; and, where interim financial 
information required to be presented by Article 3 of Regulation S-X is not 
set forth in the Prospectus, to deliver, or cause to be delivered to each 
person to whom the Prospectus is sent or given, the latest quarterly report 
that is specifically incorporated by reference in the Prospectus to provide 
such interim financial information.

	Insofar as indemnification for liabilities arising under the Securities 
Act of 1933 may be permitted to directors, officers and controlling persons 
of the Registrant pursuant to the foregoing provisions or otherwise, the 
Registrant has been advised that, in the opinion of the Securities and 
Exchange Commission, such indemnification is against public policy as 
expressed in the Act and is, therefore, unenforceable.  In the event that a 
claim for indemnification against such liabilities (other than the payment by 
the Registrant of expenses incurred or paid by a director, officer or 
controlling person of the Registrant in the successful defense of any action, 
suit or proceeding) is asserted by such director, officer or controlling 
person in connection with the securities being registered, the Registrant 
will, unless in the opinion of its counsel the matter has been settled by 
controlling precedent, submit to a court of appropriate jurisdiction the 
question whether such indemnification by it is against public policy as 
expressed in the Act and will be governed by the final adjudication of such 
issue.

	(i) The undersigned Registrant hereby undertakes that:

	(1)	For purposes of determining any liability under the Securities 
Act of 1933, the information omitted from the form of Prospectus filed as 
part of this Registration Statement in reliance upon Rule 430A and contained 
in a form of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or 
(4) or 497(h) under the Securities Act shall be deemed to be part of this 
Registration Statement as of the time it was declared effective.

	(2)	For the purpose of determining any liability under the 
Securities Act of 1933, each post-effective amendment that contains a form of 
Prospectus shall be deemed to be a new Registration Statement relating to the 
securities offered therein, and the offering of such securities at that time 
shall be deemed to be the initial bona fide offering thereof.

Re:   Registration Statement on Form S-3

Ladies and Gentlemen:

	In connection with the Registration Statement on Form S-3 filed by 
Sheldahl, Inc. with the Securities and Exchange Commission, relating to a 
public offering of up to 1,592,160 shares of common stock, $.25 par value, to 
be offered and sold by certain selling shareholders (as defined therein), 
please be advised that as counsel to the Company, upon examination of such 
corporate documents and records as we have deemed necessary or advisable for 
the purposes of this opinion, it is our opinion that:

	1.  The Company is a validly existing corporation in good standing 
under the laws of the State of Minnesota.

	2.  The shares of common stock being offered by the selling 
shareholders are duly authorized and, when issued to the selling shareholders 
and paid for as contemplated by the Purchase Agreement and the warrants, as 
applicable, included in the Registration Statement as Exhibits 4.14 and 4.16, 
respectively, will be legally and validly issued, fully paid and 
nonassessable.

	We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement, and to the reference to our firm under the heading 
"Legal Matters" in the Prospectus comprising a part of the Registration 
Statement.
						
Very truly yours,
