    Abstract: Provided is a honeycomb structure 100 including: a pillar-shaped honeycomb structure body 4 that includes a porous partition wall which defines and forms a plurality of cells 2 formed as fluid flow passages and extending from a first end face as one end face to a second end face as the other end face, and that includes a circumferential wall 3 located at an outer circumference of the honeycomb structure body; and a pair of electrodes 6 and 6 which are disposed on a side surface of the honeycomb structure body 4. Here, an open frontal area of a center part 21 is 0.70 to 0.95 times an open frontal area of an outer circumferential part 22, where the center part 21 is defined as an area from a center of the honeycomb structure body 4 to a position of 10% of a length from the center to the outer circumference in a direction toward the outer circumference in a cross-section orthogonal to an extending direction of the cells 2 of the honeycomb structure body 4, and the outer circumferential part 22 is defined as an area from the outer circumference to a position of 10% of a length from the outer circumference to the center in a direction toward the center in the cross-section. The honeycomb structure is a catalyst carrier and also serves as a heater when a voltage is applied thereto, and is able to raise a temperature thereof to a necessary temperature up to a center part thereof in a short time when a voltage is applied thereto to purify an exhaust gas.
