An exhaust gas-purifying honeycomb filter having excellent efficiency of recovering particulates collected is provided. A honeycomb structure body is formed by assembling one or more of column-like porous ceramic members in each of which a large number of through-holes are arranged in the longitudinal direction and either end of each through-hole is sealed. A porous ceramic member is a composite body made from ceramic particles and silicon. A catalyst is carried on a wall portion. The opening ratio alpha (%) of the honeycomb structure body and the amount beta (g/L) carried of the catalyst have a relation of the following expression: 9.8 - 0.125 x alpha
