Zusammenfassung:	A honeycomb filter includes a pillar-shaped honeycomb structure having a porous partition wall disposed so as to surround a plurality of cells which serve as a fluid through channel extending from a first end face to a second end face; a plugging portion provided at either an end on the first end face side or the second end face side of the cell; and a catalyst for purifying exhaust gas that is loaded on the partition wall; wherein, in the state where the catalyst is not loaded, the partition wall has a pore volume of 0.07 to 0.30 cc/g of pores having a pore diameter of 10 μm or less, an average pore diameter of 11 to 23 μm, and a porosity of 56 to 65%.
