Abstract
A honeycomb structure is provided with a pair of electrode sections disposed on the side face of the honeycomb structure section. The honeycomb structure section has an electrical resistivity of 1 to 200 Ωcm, and each of the pair of electrode sections is formed into a band-like shape extending in a cell extension direction of the honeycomb structure section. In a cross section perpendicular to the cell extension direction, one electrode section of the pair of electrode sections is disposed across the center O of the honeycomb structure section from the other electrode section of the pair of electrode sections. In a cross section perpendicular to the cell extension direction, 0.5 times the central angle of each of the electrode sections is 15 to 65°.

A honeycomb structure comprising:
- a cylindrical honeycomb structure section having porous partition walls separating and forming a plurality of cells extending from one end face to the other end face and functioning as fluid passages and an outer peripheral wall located in the outermost periphery and a pair of electrode sections disposed on the side face of the honeycomb structure section,
- wherein the honeycomb structure section has an electrical resistivity of 1 to 200 Ωcm,
- each of the pair of electrode sections is formed into a band-like shape extending in a cell extension direction of the honeycomb structure section,
- in a cross section perpendicular to the cell extension direction, one electrode section of the pair of electrode sections is disposed across the center of the honeycomb structure section from the other electrode section of the pair of electrode sections, and
- in a cross section perpendicular to the cell extension direction, 0.5 times the central angle of each of the electrode sections is 15 to 65° and
- the cells are arranged adjacent to one another in an uninterrupted manner from the one electrode section to the other electrode section.
