Exhaust gas purifying filter

An exhaust gas purifying filter used with a HC purifying catalyst carried thereon, comprising:

• a honeycomb structure part having a partition including numerous pores formed therein, and a plurality of cells divided by the partition, forming a passage for an exhaust gas;
• and
• an opening sealed portion that alternately seals an inflow end surface or an outflow end surface of the exhaust gas in the cells,
• wherein
• in a cross-section of the partition sectioned along a wall thickness direction, each pore is open at a passage surface facing the cells, having an opening end of which the opening diameter is 50 μm or larger;
• the partition includes a narrow part in a region positioned between a pair of virtual lines extending from opposing sides of the opening end to a passage surface positioned opposite to the opening end along the wall thickness direction, the narrow part having a pore diameter of 5 μm or more and the pore diameter being a minimum in the region;
• and
• the pore diameter at the narrow part is 6% or more and less than or equal to 20% of the opening diameter.
