ELECTRICALLY HEATED CATALYST DEVICE

摘要

An electrically heated catalyst device has a cylindrical outer skin part and a cell formation part. A pair of electrodes formed on the outer skin park faces relative to each other in a radial direction of the honeycomb structural body. An electrode terminal is formed on the corresponding electrode in an outer radial direction of the honeycomb structural body. A length edge line of each electrode is inclined to a virtual reference line at a predetermined angle. The virtual reference line is a virtual line defined on the outer circumferential surface of the outer skin part and is parallel to the axial direction of the honeycomb structural body. The electrode terminals are formed at a predetermined interval in the axial direction of the honeycomb structural body to make an angle of less than 180° when viewed from one end surface perpendicular to the axial direction of the honeycomb structural body.
