<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control filter capable of reducing total pressure loss. <P>SOLUTION: This exhaust emission control filter is constituted in such a way that it is provided with a honeycomb molded body having a bulkhead provided with many thin holes and an outer skin layer covering parts around the bulkhead and formed into a honeycomb shape and a plurality of cells partitioned by the bulkhead to circulate exhaust gas are composed of inlet cells opening an inlet part being an inlet side for exhaust gas and closing an outlet part being an outlet side for exhaust gas by an outlet side plug part for plugging up the outlet part of the cell and outlet cells closing an inlet part by an inlet side plug part for plugging up the inlet part of the cell and opening an outlet part to purify exhaust gas by catching particulates in exhaust gas exhausted from an internal combustion engine. When total surface area of the bulkhead provided with the bulkhead nipped by a plurality of inlet cells and nipped by the plurality of inlet cells is S1 and total surface area of the bulkheads of all the cells is S2, S1/S2 is in a scope of 0.05 to 0.09. <P>COPYRIGHT: (C)2007,JPO&INPIT |
