ELECTRIC HEATING TYPE SUPPORT, EXHAUST GAS PURIFIYING DEVICE, AND METHOD FOR PRODUCING ELECTRIC HEATING TYPE SUPPORT
An electric heating type support includes: an electrically conductive honeycomb structure comprising a pillar shaped honeycomb structure portion, the pillar shaped honeycomb structure portion comprising: 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. The pillar shaped honeycomb structure portion is composed of ceramics and a metal. The pillar shaped honeycomb structure portion contains 40% by volume or less of the metal. The welded portion of the electrically conductive honeycomb structure has a surface containing 40% by volume or more of the metal.
