发明名称 Exhaust gas purification filter
摘要 An exhaust gas purification filter capable of suppressing the generation of an excessive pressure loss due to the particulates deposited is disclosed. At least a part of a multiplicity of cells (10) surrounded by partitioning walls (11) of the honeycombed exhaust gas purification filter (1) have plugs (2, 3) on one of the two end portions thereof. At least a part of the cells to be arranged on the downstream side in the fluid path are partial plugs (3) having openings (30) allowing the fluid to flow therethrough. The pressure loss caused when the fluid entering the cells (10) passes through the partitioning walls (11) is smaller than the pressure loss caused when the exhaust gas passes through the partial plugs (3).
