A honeycomb structure includes a tubular honeycomb structure body 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 body, an electrical resistivity of the honeycomb structure body is from 1 to 200 Ωcm, each of the pair of electrode sections is formed into a band shape extending in an extending direction of the cells, the electrode section contains silicon and an aggregate, and a ratio (the silicon/the aggregate) of a volume of the silicon to be contained in the electrode section to a volume of the aggregate to be contained in the electrode section is from 60/40 to 80/20.
