Honeycomb structure, electrically heated carrier, and exhaust gas purification device

Abstract

A honeycomb structure including an electrically conductive honeycomb structure portion, comprising an outer peripheral wall, and partition walls disposed inside the outer peripheral wall and partitioning a plurality of cells forming flow paths from one end surface to the other end surface; and a pair of electrode layers provided on an outer surface of the outer peripheral wall so as to face each other across a central axis of the honeycomb structure portion; wherein a coefficient of linear expansion of the honeycomb structure portion measured according to JIS R1618:2002 when temperature is changed from 40° C. to 300° C. is 4.1×10−6/° C. or more, and the coefficient of linear expansion of the honeycomb structure portion measured according to JIS R1618:2002 when the temperature is changed from 300° C. to 800° C. is 4.2×10−6/° C. or more and 4.8×10−6/° C. or less.
