    摘要: A honeycomb structure includes a center part which has a cylindrical honeycomb structure part with a porous partition wall and an outer circumferential wall defining a plurality of cells, and which has a pair of electrodes disposed on the side surface of the honeycomb structure part. The honeycomb structure also includes an outer circumferential part disposed around the center part. The electric resistivity of the honeycomb structure part is 1-200 Ωcm. Each electrode in the electrode pair is formed in a band shape that extends in the direction that the cells extend. In a cross section, one electrode is located opposite the other electrode over the center of the honeycomb structure part. The outer circumferential part has a porous partition wall and an outer circumferential wall that define a plurality of cells. The volumetric heat capacity of the outer circumferential part is smaller than that of the center part.
