Abstract
A honeycomb structure includes a pillar-shaped honeycomb structure body having a porous partition wall defining a plurality of cells serving as fluid through channel extending from an inflow end face to an outflow end face; and a circumferential wall surrounding the partition wall, wherein in a plane orthogonal to cell extending direction, the honeycomb structure body has a circumferential cell structure, a center cell structure having a cell structure different from the circumferential cell structure, and a boundary wall, the honeycomb structure body has intersection parts of the partition wall, including basic intersection parts and thick intersection parts having a thickness larger than that of the basic intersection parts, the thick intersection parts include at least one of: first thick intersection parts and second thick intersection parts, and in the circumferential cell structure, the intersection parts at least include the circumferential basic intersection parts.
