Abstract
A honeycomb structure including a honeycomb portion having porous partition walls extending from an inflow end face to an outflow end face, an outermost peripheral wall, and a pair of electrode layers on a side surface of the honeycomb portion. Each electrode layer extends in a direction of the cells. One electrode layer is disposed on a side opposite to the other electrode layer across a center of the honeycomb portion in a cross section orthogonal to the extending direction of the cells. The honeycomb structure portion includes first cells opened on the inflow side and plugged on the outflow side, and second cells opened on the outflow side and plugged on the inflow side. A middle of each length of the pair of electrode layers is closer to the outflow side than a middle position of a length of the honeycomb portion in the extending direction of the cells.
