There is disclosed a honeycomb structure including a honeycomb structure section 4, and a pair of band-like electrode sections 21 arranged on a side surface 5 of the honeycomb structure section 4, an electrical resistivity of the honeycomb structure section 4 is from 1 to 200 ©cm, in a cross section which is perpendicular to an extending direction of cells 2, the one electrode section 21 is disposed on an opposite side of the other electrode section 21 via the center O, an angle which is 0.5 time as large as a central angle of the electrode section 21 is from 15 to 65°, and each of the electrode sections 21 and 21 is formed so as to become thinner from a center portion 21a in a peripheral direction toward both ends in the peripheral direction in the cross section which is perpendicular to the cell extending direction in a honeycomb structure 100. The honeycomb structure is a catalyst carrier, also functions as a heater, and can suppress a bias of a temperature distribution when applying a voltage. |
