摘要: This honeycomb filter is used to capture fine particles, and is provided with wall parts (13) comprising a base material having, as constituent components, a ceria-zirconia composite oxide and an inorganic binder. The wall parts (13) have a peak in the range of pore sizes from 0.01 µm to less than 1 µm, and a peak in the range of pore sizes of 1-50 µm inclusive, in a pore size distribution which is measured using the mercury penetration method, and in which the pore size and the log differential pore volume as are set as the horizontal axis and the vertical axis respectively.
