Abstract:
A honeycomb filter includes a honeycomb structure and a zeolite. The honeycomb structure has cell walls to define cells between the cell walls. The zeolite is supported on the cell walls. An amount of the zeolite is from about 80 g/L to about 150 g/L. The cells include a large volume cell and a small volume cell. A porosity of the cell walls is from about 55% to about 65%. A proportion of a sum of a pore volume A and a pore volume B relative to a total pore volume C is about 20% or less. The pore volume A indicates a pore volume of pores having a pore diameter of one half or less of the average pore diameter. The pore volume B indicates a pore volume of pores having a pore diameter of twice or more the average pore diameter.
