Abstract
An electrically heated catalytic device includes an electrically heated catalyst accommodated in an outer casing provided on an exhaust pipe. A heater ring made of an insulating material is provided adjacent to an outer peripheral edge portion of an upstream end face of the electrically heated catalyst. The heat of the electrically heated catalyst is transferred to the heater ring by generating resistive heat in the electrically heated catalyst. When the soot in exhaust gas accumulates on the surface of the heater ring, the deposits of soot is removed through combustion by the heat from the surface of the heater ring.
