An electrically heated catalyst device includes: a carrier configured to carry a catalyst; a pair of electric diffusion layers formed on an outer peripheral surface of the carrier so as to be opposed each other; and wiring members each fixed to each of the electric diffusion layers, and the carrier is electrically heated via the wiring members. Each of the electric diffusion layers is formed so as to be divided into a plurality of regions in an axial direction of the carrier. |
