| description | A honeycomb filter includes a pillar-shaped honeycomb structure body having a porous partition wall disposed to surround a plurality of cells and a plugging portion provided at an open end on a first end face side or a second end face side of the cells, wherein the partition wall is composed of a material containing cordierite as a main component, a porosity of the partition wall is 60 to 70%, an average pore diameter of the partition wall is 20 to 30 μm, an open porosity of pores existing at the partition wall surface and having equivalent circle diameters exceeding 1.5 μm is 31% or more, and, in a pore diameter distribution which indicates a cumulative pore volume of the partition wall, a half-value width of a first peak including a maximum value of a log differential pore volume is 0.20 or less. |
