The cell walls extend along a longitudinal direction of the honeycomb filter to define a plurality of cells each of which has one end and another end opposite to the one end along the longitudinal direction. A majority of the plurality of cells are sealed cells sealed at either the one end or the another end. A part of the plurality of cells are open cells open at both of the one end and the another end. A number of the open cells is from about 0.1% to about 4.9% of a number of the plurality of cells.
