| 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 each of the cells, wherein the partition wall is composed of a material containing cordierite as a main component thereof, a number per unit area of pores which exist at a surface of the partition wall and which have equivalent circle diameters exceeding 3.0 μm is 1400 per mm2 or more, and, in a pore diameter distribution which indicates a cumulative pore volume of the partition wall, with a log pore diameter on a horizonal axis and a log differential pore volume (cm3/g) on a vertical axis, a half-value width of a first peak that includes a maximum value of the log differential pore volume is 0.30 or less. |
