                       Report of Independent Accountants

We  have  audited the  consolidated  financial  statements  and the  financial
statement  schedules  of  Minnesota   Mining  and  Manufacturing  Company  and
subsidiaries  (the company) as listed  in Item  8 and  Item 14(a) of this Form
10-K.   These financial statements  and financial statement  schedules are the
responsibility  of the Company's management.  Our responsibility is to express
an  opinion on  these financial  statements and financial  statement schedules
based on our audits.

We  conducted  our  audits  in  accordance  with  generally accepted  auditing
standards.   Those standards require  that we  plan and perform  the audit  to
obtain reasonable assurance about whether the financial statements are free of
material  misstatements.    An audit  includes  examining,  on  a test  basis,
evidence supporting the amounts and  disclosures in the financial  statements.
An  audit   also  includes  assessing  the  accounting   principles  used  and
significant  estimates made by management,  as well as  evaluating the overall
financial  statement presentation.    We believe  that  our audits  provide  a
reasonable basis for our opinion.

In our opinion, the financial statements  referred to above present fairly, in
all material respects, the consolidated financial position of Minnesota Mining
and Manufacturing  Company and subsidiaries as of  December 31, 1993 and 1992,
and the consolidated results of their operations and their cash flows for each
of the three  years in the period  ended December 31, 1993 in  conformity with
generally  accepted accounting principles.   In addition, in  our opinion, the
financial statement schedules  referred to above, when  considered in relation
to the basic  financial statements taken  as a whole,  present fairly, in  all
material respects, the information required to be included therein.

As discussed in the Notes to the Financial Statements, the company changed the
fiscal year-end  of its  international companies  in 1992.   The  company also
adopted  in  1992  Statements  of  Financial  Accounting  Standards  No.  106,
"Employers' Accounting  for Postretirement Benefits Other  Than Pensions," and
No. 109, "Accounting for Income Taxes."

Notes to Financial Statements

  Accounting Policies
  Consolidation:      All    significant   subsidiaries   are    consolidated.
  Unconsolidated subsidiaries and affiliates are included on the equity basis. 

  Cash and  Cash Equivalents:  Cash  and cash equivalents consist  of cash and
  temporary investments with maturities of three months or less when purchased.

  Other  Securities:   Other securities consist  of marketable  securities and
  interest-bearing bank deposits with  varied maturity dates.  These  securities
  are employed in the  company's banking, captive insurance and  cash management
  operations.  The securities are stated at cost, which approximates fair value.

  Inventories:  Inventories are stated  at lower of cost or market,  with cost
generally determined on a first-in, first-out basis.

  Investments:  Investments  primarily include assets  from captive  insurance
and  banking   operations  and  from  venture  capital   investments.    These
investments are stated at cost, which approximates fair value.

  Other Assets:   Other assets include  goodwill, patents, other  intangibles,
deferred taxes and  other noncurrent  assets.  Other  assets are  periodically
reviewed  for  impairment  to  ensure  that  they  are  appropriately  valued.
Goodwill is generally amortized on a straight-line basis over 10 years.  Other
intangible items are amortized  on a straight-line basis over  their estimated
economic lives.

  Deferred  Income Taxes:   Deferred  income taxes  arise from  differences in
basis for tax and financial-reporting purposes.

  Revenue  Recognition:   Revenue  is recognized  upon  shipment of  goods  to
customers and upon performance of services.

  Depreciation:   Depreciation of property,  plant and equipment  is generally
computed on  a straight-line basis  over the  estimated useful lives  of these
assets.

  Research and Development:   Research  and development costs  are charged  to
operations as incurred and totaled $1.030  billion in 1993, $1.007 billion  in
1992 and $914 million in 1991.

  Foreign Currency Translation:  Local currencies are generally considered the
functional  currencies outside  the United  States, except  in countries  with
highly inflationary economies.  Assets and liabilities are translated at year-
end exchange rates for  operations in local currency environments.  Income and
expense  items are translated at  average rates of  exchange prevailing during
the   year.    Translation  adjustments   are  recorded  as   a  component  of
stockholders' equity.
   For  operations in  countries with  highly inflationary  economies, certain
financial  statement amounts are translated at historical exchange rates, with
all other assets and liabilities translated at year-end exchange rates.  These
translation  adjustments are  reflected in  the results  of operations.   They
decreased  net income  by $12  million in  1993, increased  net income  by $10
million in 1992 and decreased net income by $6 million in 1991.

  Accounting Changes
Effective  January  1,  1992,  3M's  international  companies  changed   their
reporting  period from  a fiscal  year ending  October 31  to a  calendar year
ending  December 31.  The change was  made to aid worldwide business planning,
increase efficiency and reflect  the global nature of the  company's business.
The international companies' results  of operations for the period  November 1
to  December 31, 1991, are shown in  the 1992 Consolidated Statement of Income
as  a cumulative  effect  of an  accounting change.    The cash  flows  of the
international  companies for the 14-month period November 1, 1991, to December
31, 1992, are reflected in the 1992 Consolidated Statement of Cash Flows.
  Effective  January  1,  1992,  the company  adopted  Statement  of Financial
Accounting Standards (SFAS) No. 106, "Employers' Accounting for Postretirement
Benefits  Other Than  Pensions."   This statement  requires that  the  cost of
providing postretirement  benefits  be  accrued  over  an  employee's  service
period.  In implementing this standard, the company was required to accrue the
unfunded  obligation.  The company had accrued  and funded - under a different
actuarial methodology - a substantial amount of these benefits since 1977.  In
implementing this  standard,  the company  elected  to record  the  transition
obligation using the immediate recognition option.
  Also   effective  January  1,  1992,  the  company  adopted  SFAS  No.  109,
"Accounting for Income Taxes."  This statement requires an asset and liability
approach for financial  accounting and reporting of income  taxes.  Under this
approach, deferred  taxes are recognized  for the  estimated taxes  ultimately
payable or recoverable based on enacted tax law.  Changes in enacted tax rates
will be reflected in the tax provision as they occur.
  Adoption of these accounting changes, in aggregate, did  not have a material
impact on 1992 results of operations.  
  The  table below shows the components of the cumulative effect of accounting
changes.

  Legal Settlement and Special Charges
In  December 1992,  Johnson  &  Johnson  agreed  to pay  3M  $129  million  in
settlement of  a patent lawsuit involving 3M orthopedic casting materials.  3M
received payment in January 1993.

In 1992,  3M  recorded $115  million of  special charges  designed to  enhance
competitiveness and productivity.   About 75 percent of these  charges related
to asset write-downs, including rationalization of manufacturing operations.

  Long-Term Debt
 Employee Stock Ownership Plan:  In 1989,  the company established an Employee
Stock Ownership Plan  (ESOP).  The  ESOP borrowed $548  million.  Because  the
company  has guaranteed  repayment  of the  ESOP  debt, the  debt and  related
unearned compensation are recorded on the Consolidated Balance Sheet.
 Medium-Term Notes:   3M maintains a  shelf registration  with the  Securities
and Exchange Commission that provides the means to offer medium-term notes not
to exceed $601 million.  As  of December 31, 1993, $502 million  was available
for future  financial  needs.   The company  entered into  interest rate  swap
agreements  to achieve  variable interest  rates below  U.S. commercial  paper
rates  for  notes  outstanding.    The  effective  rate  of  these  agreements
approximated 2.5 percent at year-end 1993.
 Other  Borrowings:   These  are primarily  borrowings  of 3M's  international
companies and municipal  bond issues  in the  United States.   Interest  rates
range mainly from 2.3 to 11.0 percent.

 Maturities of long-term  debt for the next  five years are as  follows: 1994,
$79  million; 1995,  $168 million; 1996,  $44 million; 1997,  $41 million; and
1998, $159 million.
 Interest  payments included  in  the  Consolidated  Statement of  Cash  Flows
totaled $53  million in 1993,  $88 million in 1992  and $118 million  in 1991.
For the calendar year 1992, interest payments were $79 million.
 The  company  estimates  that  the  fair  value  of  long-term  debt  is  not
materially different than the carrying amount of this debt.

  Other Financial Instruments
The company  has entered  into interest  rate and currency  swaps, as  well as
forward interest rate  agreements, with face amounts of  $605 million and $308
million, respectively,  as of December 31,  1993, and 1992.   The company uses

                                      27
<PAGE>

these  instruments to manage risk from interest rate and currency fluctuations
and to  lower its  cost of  borrowing.   The unrealized  gains and  losses are
deferred until the  underlying transactions are realized.  As  of December 31,
1993, the unrealized gains and losses were not material.
 The company also had foreign exchange forward and option contracts with  face
amounts  of $704 million and $785 million, respectively, at December 31, 1993,
and 1992.   The  company uses these  financial instruments primarily  to hedge
transactions  denominated in  foreign currencies,  thereby reducing  risk from
exchange rate  fluctuations in the regular course of its global business.  The
net unrealized  gain on  these  contracts as  of December  31,  1993, was  not
material.

 For calendar year 1992, income tax payments were $714 million.
 At December 31, 1993, there were approximately $2.850 billion of retained
 earnings attributable to our international companies that are considered to
 be permanently invested.  No provision has been made for taxes that might be
 payable if these earnings were remitted to the United States.  It is not
 practical to determine the amount of incremental tax that might arise should
 these earnings be remitted.

  Retirement Plans
3M has  various company-sponsored retirement plans  covering substantially all
U.S. employees and many employees outside the United States.  Pension benefits
are based principally on an employee's years of  service and compensation near
retirement.    Plan  assets  are  invested  in  common   stocks,  fixed-income
securities, real estate and other investments.
 The company's  funding  policy  is to  deposit  with an  independent  trustee
amounts at least equal to those  required by law.  A trust fund  is maintained
to provide pension benefits to plan participants  and their beneficiaries.  In
addition,  a number  of  plans  are  maintained  by  deposits  with  insurance
companies.
  The charge to income  relating to these plans was $203 million in 1993, $178
million in 1992 and $133 million in 1991.

  Other Postretirement Benefits
The company provides health care and life insurance benefits for substantially
all  of its  U.S. employees  who reach  retirement age  while employed  by the
company.   The  company has set  aside funds  with an  independent trustee for
these postretirement  benefits and makes  periodic contributions to  the plan.
The assets  held by the trustee are invested in common stocks and fixed-income
securities.   Employees outside the  United States are  covered principally by
government-sponsored plans  and the cost  of company-provided plans  for these
employees is not material.
 The table below sets forth the components of the net  periodic postretirement
benefit cost and  a reconciliation of the funded  status of the postretirement
benefit plan for U.S. employees.

 The  accumulated postretirement  benefit obligation and  related benefit cost
are determined through the application of relevant actuarial assumptions.  The
company anticipates its  health care cost trend rate to  slow from 7.5 percent
in  1994 to 5.0  percent in 2003,  after which the  trend rate is  expected to
stabilize.   The  effect of  a one  percentage point  increase in  the assumed
health care  cost trend rate for  each future year would  increase the benefit
obligation by  $57 million and the current year benefit expense by $4 million.
Other  actuarial assumptions include an  expected long-term rate  of return on
plan assets of 9.0 percent (before taxes applicable to a portion of the return
on plan assets), and a discount rate of 7.25 percent.
 The charge to  income relating to  these plans was $54  million in 1993,  $50
million in 1992 and $51 million in 1991.

  Other Postemployment Benefits
 In 1992, the Financial  Accounting Standards Board issued Statement  No. 112,
"Employers' Accounting for Postemployment  Benefits."  Postemployment benefits
include,  but  are  not limited  to,  disability,  severance  and health  care
benefits.   3M will  adopt this standard in  the first quarter  of 1994.  This
adoption will have a diminimus effect on the company's results of operations.

  Employee Stock Ownership Plan
The   company  maintains   an  Employee   Stock  Ownership  Plan   (ESOP)  for
substantially all full-time U.S. employees.  This plan was established in 1989
as  a  cost-effective  way  of  funding certain  employee  retirement  savings
benefits, including  the company's  matching  contributions under  its  401(k)
employee savings plan.  The  ESOP borrowed $548 million and used  the proceeds
to purchase 7.7  million shares of the company's common stock, previously held
in  treasury.  The  debt is being serviced  by dividends on  stock held by the
ESOP and by  company contributions.   These  contributions are  reported as  a
benefit expense.

  Employee Savings Plan
The company  sponsors an  employee savings  plan under  Section 401(k) of  the
Internal  Revenue Code.   This  plan covers  substantially all  full-time U.S.
employees.  The company matches  employee contributions of up to 6  percent of
compensation at rates  ranging from 35  to 85 percent, depending  upon company
performance.   Amounts  charged against  income were $29  million in  1993 and
1992, and $28 million in 1991.

  General Employees' Stock Purchase Plan
Participants in the General Employees' Stock Purchase Plan are granted options
at 85 percent  of market value at  the date of grant.   At December 31,  1993,
there were  23,216 participants in the plan, with 58,058 employees eligible to
participate.  Options must be exercised within 27 months from date of grant.
