ELECTRIC HEATING TYPE SUPPORT, EXHAUST GAS PURIFYING DEVICE, METHOD FOR PRODUCING ELECTRIC HEATING TYPE SUPPORT, JOINED BODY, AND METHOD FOR PRODUCING JOINED BODY

摘要

An electric heating type support includes: an electrically conductive honeycomb structure including a pillar shaped honeycomb structure portion composed of conductive ceramics, the pillar shaped honeycomb structure portion including: an outer peripheral wall; and porous partition walls disposed on an inner side of the outer peripheral wall, the porous partition walls defining a plurality of cells, each cell penetrating from one end face to other end face to form a flow path; and a pair of metal terminals disposed so as to face each other across a central axis of the pillar shaped honeycomb structure portion, each metal terminal being joined to a surface of the electrically conductive honeycomb structure via a welded portion so as to follow a surface shape of the electrically conductive honeycomb structure.
