<p>A honeycomb filter (1) comprises a honeycomb structure having a large number of through channels (13) formed in the axial direction and partitioned by porous partition walls (2), wherein specified through channels (13) are plugged only on one end face (6) at the same side out of two end faces. This honeycomb filter (1) shows less pressure loss, and is hardly clogged with solids that cannot be extinguished by combustion such as ash, iron oxide, and the like. Furthermore, an unwanted discharge of particulates deposited in through channels (13) of the filter (1) in a larger amount due to pulsation even under conditions that the exhaust gas from an engine greatly pulsates can be effectively suppressed. This filter (1) is also usable as an element for exhaust gas purification system, or a part of composite filter in addition to the use for an exhaust gas purification filter for gasoline engines. The production method therefor is also disclosed. <IMAGE></p> |
