The wall-flow honeycomb structure (1) includes inlet cells (10) clogged on the downstream side of the exhaust gases, outlet cells (11) neighboring the inlet cells (10) and clogged on the upstream side of the exhaust gases, filter cellular walls (12) demarcating the inlet cells (10) and the outlet cells (11) and having pores, and a catalytic layer (13) formed on the surface of the filter cellular walls (12) and/or the surface of the pores of the filter cellular walls. The upstream-side straight honeycomb structure (2) is disposed on the upstream side of the exhaust gases with respect to the wall-flow honeycomb structure (1), is provided integrally with the wall-flow honeycomb structure (1), and includes upstream-side straight cells (20) in which the exhaust gases flow straight, and upstream-side cellular walls (21) demarcating the upstream-side straight cells.

摘要： A porous honeycomb structure body, having honeycomb shaped cell walls and a large number of cells surrounded with the honeycomb shaped cell walls, and a related manufacturing method are disclosed. The cell walls have a principal composition of cordierite in a chemical composition of 45-55 % by weight of SiO 2 , 33-42 % by weight of Al 2 O 3 and 12-18 % by weight of MgO. The cell walls have fine pores formed in a distribution under which a fine pore bulk, having pore diameters of 5µm or less, is less than 15% of an entire pore bulk and a fine pore bulk, having pore diameters exceeding 25µm, is less than 10% of the entire pore bulk. The porous honeycomb structure body has porosity ranging from 40 to 60% and has a thermal expansion coefficient of 0.7 × 10 -6 /°C or less at temperatures ranging from 40 to 800°C.
