Abstract
An exhaust gas filter is formed of ceramic honeycomb structure and provided with large number of passages defined by porous thin separator walls. The passages are composed of exhaust gas inlet passages and outlet passages which are alternately arranged. The honeycomb structure is further provided with exhaust gas blowing passages through which one part of exhaust gases entering into the inlet passages is discharged, without passing through minute pores of the porous thin separator walls, resulting in reducing the pressure loss of the exhaust gases.
