The electrically heated catalyst comprising: a heat generation element; an electrode; a case; an electrode chamber; and an electrically insulating holding member that is inserted between the outer peripheral surface of the heat generation element and the case, and has an abutment joint portion formed by a pair of end faces which connect from an upstream side end portion to a downstream side end portion of the holding member, and which are arranged in opposition to each other, and an opening portion which is constructed so as to form a predetermined space connected with the electrode chamber in the surrounding of the electrode. The abutment joint portion is arranged in a position which excludes the opening portion, and in which it is not exposed to the electrode chamber.
