Honeycomb filter and production method for honeycomb filter

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