Abstract
An electrically heated catalyst device that can uniformly heat a catalyst via comb-shaped electrodes even when current is repeatedly made to flow through the electrodes. The device includes a carrier having a metal catalyst supported thereon, a pair of comb-shaped electrodes each having wire portions, a base layer between each comb-shaped electrode and the carrier, and a fixation layer for fixing each wire portion on the base layer. The fixation layer is rectangular in shape when the outer peripheral surface of the carrier is seen from a direction orthogonal to the central axis of the carrier along the longitudinal direction of the device. A pair of opposite first sides of the fixation layer are parallel with the extending direction of each wire portion on opposite sides thereof, and a pair of second sides coupling opposite ends of the first sides are orthogonal to the extending direction of each wire portion.
