To provide a honeycomb filter having an excellent NOx removal rate.

The honeycomb filter includes a honeycomb-structured body, which is constituted so that a large number of cells are parted from one another by cell walls and arranged in parallel in the longitudinal direction of the honeycomb-structured body and each of the large number of cells is sealed at one end thereof, and zeolite deposited on the cell wall of the honeycomb-structured body. The amount of the zeolite deposited on the cell wall is 80-150 g/L. The large number of cells include large-volume cells and small-volume cells. The cell wall of the honeycomb-structured body has 55-65% porosity and pores of 15-25 μm average pore diameter. A pore diameter distribution of the cell wall of the honeycomb-structured body is characterized in that the sum of the pore volume A of pores having the pore diameter equal to or smaller than the half of the average pore diameter and the pore volume B of pores having the pore diameter equal to or larger than the twice of the average pore diameter is ≤20% of the total pore volume C.
