A honeycomb structure includes a cylindrical honeycomb structure section having porous partition walls to define and form a plurality of cells, and an outer peripheral wall, and a pair of electrode sections disposed on a side surface of the honeycomb structure section. An electrical resistivity of the honeycomb structure section is from 1 to 200 Ωcm, and each of the pair of electrode sections is constituted of a laminated body of two or more electrode bodies. An area of the electrode body disposed closest to an outer peripheral wall side is larger than an area of the other electrode body, and in a cross section perpendicular to a cell extending direction, a center angle of the electrode body disposed closest to the outer peripheral wall side is larger than a center angle of the other electrode body.
