Ceramic honeycomb filter

摘要

A ceramic honeycomb filter (10) comprises a ceramic honeycomb structure (1) having porous partition walls (3) defining several flow paths (4) for flowing exhaust gas (20a) through the porous partition walls to remove particulates from the exhaust gas. One end of each flow path is provided with a sealer (5) such that the sealer of the flow path in the inlet and outlet of the honeycomb structure are in a desired pattern. The sealer has pores. At least part of the pores have circular cross-sections.
