A ceramic honeycomb filter comprising pluralities of flow paths partitioned by porous cell walls, a fluid entering one end being discharged from the other end; pluralities of flow paths comprising intake flow paths which are open on the one end side and sealed on the other end side, and discharge flow paths which are sealed on the one end side and open on the other end side; in a cross section perpendicular to the longitudinal direction of the flow paths, (a) the cross section areas of the intake flow paths being larger than those of the discharge flow paths; (b) the intake and discharge flow paths having octagonal cross section shapes with four-fold rotation symmetry each obtained by cutting off four corners from a square; (c) the intake and discharge flow paths being alternately arranged in a first direction and a second direction perpendicular to the first direction, such that their opposing sides are parallel; (d) the opening ratio of the intake flow paths being 45-60%; (e) the number of the flow paths per cm2 being 30-60; (f) the thickness t1 of a cell wall between an intake flow path and a discharge flow path adjacent to that intake flow path being 0.150-0.260 mm; and (g) the thickness t2 of a cell wall between adjacent intake flow paths meeting 1.175 < t2/t1 < 1.6.
