<p>A honeycomb structure is provided with: a cylindrical honeycomb structure section 4 having porous partition walls 1 separating and forming a plurality of cells 2 and an outer peripheral wall 3 and a pair of electrode sections 21 disposed on the side face 5 of the honeycomb structure section 4. The honeycomb structure section 4 has an electric resistivity of 1 to 200 ©cm, and each of the pair of electrode sections 21 is formed into a band-like shape extending in a cell 2 extension direction of the honeycomb structure section 4. In a cross section perpendicular to the cell 2 extension direction, one electrode section 21 of the pair of electrode sections 21 is disposed across the center O of the honeycomb structure section 4 from the other electrode section 21 of the pair of electrode sections 21. In a cross section perpendicular to the cell 2 extension direction, 0.5 time the central angle of each of the electrode sections 21 is 15 to 65°. There is provided a honeycomb structure which functions not only as a catalyst carrier, but also as a heater by applying a voltage and which can suppress bias of a temperature distribution upon applying the voltage.</p> |
