内容: | A ceramic honeycomb filter comprises a ceramic honeycomb structure having porous partition walls (11b) defining a plurality of flow paths (11c) for flowing an exhaust gas through said porous partition walls to remove particulates from said exhaust gas, predetermined flow paths among said flow paths being sealed at their ends, a pitch of said porous partition walls being 2.54 mm or less, and at least some of said sealers (12a, 12b) sealing flow paths except for those near an outer periphery wall (11a) projecting from the end surfaces of said partition walls by 0.01-5 mm in a flow path direction. |
