Gentlemen and Ladies:

You
have requested our opinion with respect to the offering by you, IntriCon Corporation, a
Pennsylvania corporation (the Company), pursuant to a Registration Statement
on Form S-8 (the Registration Statement) to be filed under the Securities Act
of 1933, as amended (the Act), of up to 175,000 shares of the Companys
common stock, par value $1.00 per share (the Option Shares), issuable upon the
exercise of options (Options) available for grant under the Companys
Amended and Restated Non-employee Directors Stock Option Plan (the Plan)
as a result of an amendment to the Plan.

We
have examined and relied upon originals, or copies certified or otherwise identified to
our satisfaction, of such documents and corporate and public records as we deemed
necessary as a basis for the opinion hereinafter expressed. With respect to such
examination, we have assumed the genuineness of all signatures appearing on all documents
presented to us as originals, and the conformity to the originals of all documents
presented to us as conformed or reproduced copies. Where factual matters relevant to such
opinion were not independently established, we have relied upon representations of
executive officers of the Company.

In
rendering this opinion, we have assumed that (i) the Option Shares will be issued in
accordance with the terms and conditions of the Plan, (ii) at the time of issuance of any
Option Shares, there shall be a sufficient number of duly authorized and unissued shares
of the Companys common stock to accommodate the issuance of the Option Shares, and
(iii) the per share consideration received by the Company in exchange for the issuance of
any Option Shares shall not be less than the par value per share of the Companys
common stock.

This
opinion is limited to the laws of the Commonwealth of Pennsylvania. In rendering this
opinion, we have assumed compliance with all other laws, including federal laws and state
securities laws.

Based
upon and subject to the foregoing and the qualifications and limitations set forth below,
we are of the opinion that:

The
Option Shares, when sold, paid for and issued as contemplated by the terms of the Plan,
will be validly issued, fully paid and nonassessable.

---

This
opinion is given as of the date hereof. We assume no obligation to update or supplement
this opinion to reflect facts or circumstances that may hereafter come to our attention or
any changes in laws that may hereafter occur.

This
opinion is strictly limited to the matters stated herein and no other or more extensive
opinion is intended, implied or to be inferred beyond the matters stated herein.

We
hereby consent to the use of this opinion as Exhibit 5.1 to the Registration Statement,
and to the use of our name as your counsel in connection with the Registration Statement
and in the Prospectus forming a part thereof. In giving this consent, we do not thereby
concede that we come within the categories of persons whose consent is required by the Act
or the General Rules and Regulations promulgated thereunder.
