Honeycomb structure

摘要

A honeycomb structure including: a tubular honeycomb structure part having porous partition walls and an outer peripheral wall; and a pair of electrode parts arranged on a side surface of the honeycomb structure part, an electrical resistivity of the honeycomb structure part is from 1 to 200 Ωcm, each of the pair of electrode parts is formed into a band-like shape, the one electrode part is disposed opposite to the other electrode part via the center of the honeycomb structure part, and a distance from one end portion in the extending direction of the cells to an end portion of the electrode part which faces the one end portion of the honeycomb structure part in the extending direction of the cells is from 1 to 10% of a length of the honeycomb structure part in the extending direction of the cells.

1. A honeycomb structure comprising:
a tubular honeycomb structure part having porous partition walls with which a plurality of cells extending from one end surface to the other end surface are formed to become through channels of a fluid, and an outer peripheral wall positioned on an outermost periphery; and a pair of electrode parts arranged on a side surface of the honeycomb structure part, wherein an electrical resistivity of the porous partition walls and the outer peripheral wall of the honeycomb structure part is from 1 to 200 Ωcm, each of the pair of electrode parts is formed into a band-like shape extending in a direction in which the cells of the honeycomb structure part extend, in a cross section perpendicular to the cell extending direction, the one electrode part in the pair of electrode parts is disposed opposite to the other electrode part in the pair of electrode parts via the center of the honeycomb structure part, and a distance from one end portion of the honeycomb structure part in the cell extending direction to an end portion of the electrode part which faces the one end portion of the honeycomb structure part in the cell extending direction is from 1 to 10% of a length of the honeycomb structure part in the cell extending direction.
