Abstract: A honeycomb structure has porous partition walls defining and forming a plurality of cells communicating between two end faces, and a circumferential wall formed integrally with the partition walls. The cells include partial cells positioned in an outermost circumferential portion of the honeycomb structure and being partially in contact with the circumferential wall, and normal cells other than the partial cells. As to the normal cells, a plugging portion is formed in one end portion of each normal cell, and as to the partial cells, in the partial cells in which the plugging portion to be formed in one end portion thereof, the plugging portion is not formed in at least a part of a partial cell in which an area ratio obtained by Equation (1) is smaller than 80%: the area ratio(%)=an area of the partial cell/an area of the normal cell×100  (1).

Abstract: A honeycomb filter includes a pillar-shaped honeycomb substrate having a porous partition wall disposed so as to surround a plurality of cells serving as a fluid through channel extending from a first end face to a second end face; and a plugging portion provided at an open end on the first end face side or the second end face side of each of the cells, wherein the partition wall constituting the honeycomb substrate is composed of a ceramic porous material, a ratio of a volume of pores having a pore diameter of 10 μm or less with respect to a total pore volume of the partition wall measured by a mercury press-in method is 85 to 95%, and an average pore diameter of the partition wall measured by the mercury press-in method is 4 to 10 μm.
