The honeycomb filter 30 is formed by laminating, in the longitudinal direction, sheet-like members having a plurality of through holes, and supports a perovskite-type oxide. The honeycomb structure 40 is formed by joining porous honeycomb units having a plurality of through holes by a sealing material layer, and supports precious metals and an NOx storage agent. The exhaust gas cleanup system 10 removes and burns particulate materials contained in an exhaust gas by the honeycomb filter 30, and converts NOx, CO, and HC by the honeycomb structure 40.

    摘要： An object of the present invention is to provide a honeycomb structural body with a long service life, which can reduce a pressure loss to a low level upon collecting particulates and maintain the pressure loss at the low level for a long time even after regenerating processes. The honeycomb structural body includes a columnar porous ceramic block in which a large number of through holes are placed in parallel with one another in the length direction with a wall portion interposed therebetween. Herein, the large number of through holes are constituted by a group of large-capacity through holes, each of which is sealed at one end of the honeycomb structural body so that the total sum of the areas on a cross section perpendicular to the length direction is made relatively great, and a group of small-capacity through holes, each of which is sealed at the other end of the honeycomb structural body so that the total sum of the areas on the cross section is made relatively small, and a surface roughness Ry of the wall face of the through hole is set in a range from 10 to 100 µm.
