There is disclosed a honeycomb structure which is a catalyst carrier and also functions as a heater when a voltage is applied thereto, and which further has excellent heat shock resisting properties. A honeycomb structure 100 includes a tubular honeycomb structure body 4 having porous partition walls 1 to define and form a plurality of cells 2, and an outer peripheral wall 3; and a pair of electrode sections 21 disposed on a side surface 5 of the honeycomb structure body 4, an electrical resistivity of the honeycomb structure body 4 is from 1 to 200 ©cm, each of the pair of electrode sections 21 is formed into a band shape extending in an extending direction of the cells 2, the electrode section 21 is constituted of a porous body in which particles made of silicon carbide as an aggregate are bound by a binding material, silicon carbide as the aggregate constituting the electrode sections 21 contains ²-SiC having a stacking fault of 2% or less, and the binding material constituting the electrode sections 21 contains silicon and a metal silicide. |
