Abstract:
1. An electrically-heated catalyst comprising: a carrier; an electrically conductive underlying layer bonded to the external wall of the carrier; an electrode portion fixed to an outside surface of the electrically conductive underlying layer; and an electrically conductive fixing layer fixed to a part of the outside of the electrode portion; wherein the electrically conductive underlying layer has a coefficient of thermal expansion between a coefficient of thermal expansion of the carrier and a coefficient of thermal expansion of the electrode portion, wherein the electrically conductive fixing layer has a coefficient of thermal expansion between the coefficient of thermal expansion of the electrode portion and the coefficient of thermal expansion of the electrically conductive underlying layer, and wherein the electrode portion is fixed to the carrier by bonding the electrically conductive fixing layer to the electrically conductive underlying layer and to the electrode portion.
