Abstract
An electrically heated catalytic device includes a carrier that supports a catalyst, a surface electrode provided on an outer circumferential surface of the carrier, and metal electrodes arranged side by side on the surface electrode. The surface electrode includes an arrangement region where the metal electrodes are arranged and a non-arrangement region where the metal electrodes are not arranged. The metal electrodes are spaced apart from one another in an axial direction of the carrier in the arrangement region. The non-arrangement region is adjacent to the arrangement region in the axial direction of the carrier. An electrical resistance of the non-arrangement region is higher than an electrical resistance of the arrangement region in the surface electrode.
