Honeycomb structure

A honeycomb structure, comprising:

• a porous partition wall that defines and forms a plurality of cells, the plurality of cells extending from one end face to another end face to become through channels of a fluid;
• a tubular honeycomb structure body that includes a circumferential wall positioned at an outermost circumference;
• and
• a pair of electrode members arranged at a side surface of the honeycomb structure body, wherein
• the honeycomb structure body has an electrical resistivity of 1 to 200 Ωcm,
• the respective pair of electrode members are formed into a band-like shape extending in a direction in which the cells of the honeycomb structure body extend,
• in a cross section perpendicular to the cell extending direction, one of the electrode members in the pair of electrode members is arranged opposite to another of the electrode members in the pair of electrode members sandwiching a center of the honeycomb structure body,
• one or more of slits are formed at the honeycomb structure body, the slit being open to a side surface, and
• at least the one slit is formed so as not to intersect with a straight line connecting center portions of the respective pair of electrode members in the cross section perpendicular to the cell extending direction.
