ELECTRICALLY HEATED CATALYST APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

An electrically heated catalyst apparatus includes a carrier, a pair of surface electrodes, a wiring and a plurality of fixed layers. The carrier is formed of ceramics on which a catalyst is carried. The pair of surface electrodes face each other and are extended in an axial direction of the carrier on an outer peripheral surface of the carrier. The wiring is formed into a pectinate shape and is configured to supply electric power from an outside of the electrically heated catalyst apparatus to the surface electrode. The plurality of fixed layers is configured to fix the wiring on the surface electrode. The electrically heated catalyst apparatus is formed so that the carrier is electrically heated through the surface electrode. Elongation of the wiring is 15% or more.
