Abstract

See full text

An object of the present invention is to provide a honeycomb filter capable of preventing depth filtration and achieving a combination of high collection efficiency and low pressure loss. The honeycomb filter of the present invention comprises a ceramic honeycomb substrate in which a multitude of cells through which a fluid flows are disposed in parallel in a longitudinal direction and are separated by cell walls, each cell being sealed at an end section at either the fluid inlet side or the fluid outlet side, and a filter layer which, among the surfaces of the cell walls, is formed on the surface of the cell walls of those cells in which the end section at the fluid inlet side is open and the end section at the fluid outlet side is sealed, wherein the filter layer is composed of a plurality of spherical ceramic particles, and crosslinking bodies which bind the spherical ceramic particles to each other by crosslinking the spherical ceramic particles, and the spherical ceramic particles and the crosslinking bodies form a three-dimensional network structure.
