Honeycomb filter

A honeycomb filter comprising:

• a pillar-shaped honeycomb structure body having a porous partition wall disposed to surround a plurality of cells which serve as fluid through channels 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 plurality of cells,
• wherein a porosity of the partition wall determined by structural analysis is greater than 52% and less than 62%, and
• wherein, in a pore diameter distribution of the partition wall obtained by structural analysis, in the case where the pore diameter (μm) whose cumulative pore volume is 10% of the total pore volume is denoted by D10, the pore diameter (μm) whose cumulative pore volume is 50% of the total pore volume is denoted by D50, and the pore diameter (μm) whose cumulative pore volume is 90% of the total pore volume is denoted by D90, all of the following equations (1) to (6) are satisfied
• 3.9 μm<D10≤6.2 μm (1)
• 10.5 μm<D50<16.6 μm (2)
• 28.3 μm<D90<38.7 μm (3)
• (log D90−log D10)/log D50<0.80 (4)
• log D90/log D50<1.36 (5)
• log D50/log D10<1.56 (6).
