Abstract

A honeycomb filter includes a plurality of honeycomb fired bodies. Each of the plurality of honeycomb fired bodies includes an outer wall, a plurality of cells, and porous cell walls. The plurality of cells include exhaust gas introduction cells each having an open end at an exhaust gas inlet side and a plugged end at an exhaust gas outlet side and exhaust gas emission cells each having an open end at the exhaust gas outlet side and a plugged end at the exhaust gas inlet side. Sub-cells adjacent to the outer wall include exhaust gas introduction sub-cells among the exhaust gas introduction cells and exhaust gas emission sub-cells among the exhaust gas emission cells. A total volume of the exhaust gas emission sub-cells adjacent to the outer wall is greater than a total volume of the exhaust gas introduction sub-cells adjacent to the outer wall.
