| description | To provide a honeycomb filter which is excellent in capturing performance and has pressure loss reduced.SOLUTION: The honeycomb filter comprises columnar honeycomb structure parts 4 having porous bulkheads 1 arranged to surround a plurality of cells 2 extending from a first end face 11 to a second end face 12, and sealing parts 5 arranged at opening parts at one side of the cells. When pore sizes (μm) at which cumulative pore volumes are equal to 10%, 50% and 90% of total pore volumes are defined as D10, D50 and D90 respectively in a pore size distribution of the bulkheads determined by structural analysis, all of the following formulas are satisfied: 8.4 μm |
