摘要： A honeycomb structure including a tubular honeycomb structure portion having: porous partition walls with which a plurality of cells extending from one end surface to the other end surface are formed to partition through channels of a fluid; and an outer peripheral wall positioned on an outermost periphery, an electrical resistivity of the partition walls is from 1 to 200 Ωcm, at least a part of the outer peripheral wall is formed by a low Young's modulus portion configured to have a Young's modulus lower than that of the partition walls, and a ratio of the Young's modulus of the low Young's modulus portion to the Young's modulus of the partition walls is from 2 to 95%. Provided is a honeycomb structure which is a catalyst carrier and also functions as a heater when a voltage is applied thereto and which has an excellent heat shock resistance.
