HONEYCOMB FILTER
A honeycomb filter comprising a pillar-shaped honeycomb structure body having a porous partition wall and a plugging portion, wherein a thickness of the partition wall is 0.257 mm or less, a porosity of the partition wall is 52 to 57%, an average pore diameter of the partition wall is 6 to 13 µm, a number per unit area of pores which exist at a surface of the partition wall and which have equivalent circle opening diameters exceeding 3 µm is 800 to 1500 /mm2, an average equivalent circle opening diameter of pores which exist at a surface of the partition wall and which have equivalent circle opening diameters exceeding 3 µm is 8.0 to 12.0 µm, and in a pore diameter distribution of the partition wall,D10 is 2.0 to 5.5 µm,D90 is 13.0 to 25.5 µm, and(Log(D90)-Log(D10))/Log(D50) is 0.84 or less.
