A ceramic honeycomb filter comprising a honeycomb structure having a large number of flow paths partitioned by porous cell walls; and plugs formed in the flow paths alternately on the exhaust gas inlet and outlet sides; the thickness W (mm) and permeability κ (µm 2 ) of the cell wall and the length L (mm) and cross section area A (mm 2 ) perpendicular to the length direction of the flow path meeting the relations of 0.1 ≤ W ≤ 0.5, 8 ≤ κ/W ≤ 26.7, and 125 ≤ L/A 0.5 ≤ 360.
