Abstract:
There is provided a honeycomb filter including a honeycomb base material including a porous partition wall parent material; plugged portions arranged in open frontal areas of predetermined cells in an end surface on an inflow side of the fluid, and open frontal areas of the remaining cells in an end surface on an outflow side of the fluid; and a porous collecting layer disposed on the surface of the partition wall parent material in the remaining cells. In a cross section orthogonal to an extending direction of the cells, a shape of the cells is a rectangular shape, and a thickness of a portion of the collecting layer which is positioned in each of corner portions of each of the cells is from one to three times that of a portion of the collecting layer which is positioned in the center of each of sides of the cell.
