Abstract
An electrically heated catalyst device includes a catalyst support including a ceramics, on which a catalyst is supported, a pair of surface electrodes disposed on an outer surface of the catalyst support, the surface electrodes being disposed opposite to each other and extending in an axial direction of the catalyst support, and a wiring line that externally supplies electric power to the surface electrodes, in which the catalyst support is electrically heated through the surface electrodes. A wrought member made of metal is buried in the surface electrodes, the wrought member extending in the axial direction of the catalyst support. With the configuration like this, the spreading of electric currents in the catalyst-support axis direction can be maintained even when cracks occur in the catalyst-support circumference direction in the surface electrodes.
