    摘要: A honeycomb filter includes a cell having one open end and another closed end that serves as a fluid flow path and a cell having one closed end and another open end, wherein the cells are alternately disposed. The honeycomb filter includes an undeposited region in an upstream region of a partition portion, which has no trapping layer and has a length of 5% or more and 30% or less of the length of the inlet cell. The upstream region of the partition portion includes an undeposited region having an area of 10% or more of that of the cell in a cross-section perpendicular to the exhaust gas flow direction. The undeposited region with no trapping layer in the upstream region decreases the permeation resistance of the partition portion in the upstream region and facilitates fluid passage through the partition portion in the upstream region.
