         Re:      Registration Statement on Form S-8 for 2005
                  Equity Compensation Plan

Ladies and Gentlemen:

         We are furnishing this opinion to you in our capacity as counsel to
Rogers Corporation, a Massachusetts corporation (the "Company"), in connection
with the preparation and filing of the Registration Statement on Form S-8 to
which a copy of this opinion will be attached as an exhibit (the "Registration
Statement"), relating to the approval and adoption of the Company's 2005 Equity
Compensation Plan (the "Plan") and the registration of 1,100,000 shares of the
Company's capital stock, par value $1.00 per share (the "Shares"), that the
Company may issue pursuant to the Plan.

         As such counsel, we have examined the corporate records of the Company,
including its Restated Articles of Organization, as amended, Amended and
Restated Bylaws, minutes of meetings of its Board of Directors and shareholders,
and such other documents as we have deemed necessary as a basis for the opinions
herein expressed.

         We are attorneys admitted to practice in The Commonwealth of
Massachusetts. We express no opinion as to the laws of any jurisdiction other
than the laws of the United States of America and The Commonwealth of
Massachusetts, and also express no opinion with respect to the blue sky or
securities laws of any state, including Massachusetts.

         Based upon the foregoing, and having regard for such legal
considerations as we deemed relevant, we are of the opinion that, upon issuance
and delivery of the Shares against payment therefor in accordance with the terms
of the Plan and any agreement thereunder, the Shares will be validly issued,
fully paid and nonassessable.

         The foregoing assumes all requisite steps will be taken to comply with
the requirements of the Securities Act of 1933 and applicable requirements of
state laws regulating the offer and sale of securities.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement.


                                                     Very truly yours,

                                                     /s/ Goodwin Procter LLP
                                                     -----------------------
