Abstract

PURPOSE: To enhance collecting efficiency of carbon fine particles as well as to prolong a period capable of continuously using the titled structure by forming an exhaust gas purifying part by plural layers of ceramic porous materials different in the mesh size of a ceramic skeleton.
CONSTITUTION: An exhaust gas purifying part 1 is formed from a ceramic porous material having a plurality of complicatedly commingled and crossed continuous pores opened to the outside and a three-dimensional net like skeletal and consists of two layer parts of an upstream side purifying part 101 made of a ceramic skeletal having a mesh slightly coarser than that of said porous material and a downstream side purifying part 103 made of a ceramic skeletal having a slightly finer mesh. In addition, an outer wall 2 is formed by a ceramic porous material having a fine mesh and said purifying part 1 and the outer wall 2 consist of ceramic skeletons 1b, 2b having three-dimensional reticulate structures with voids 1a, 2a and both of these ceramic skeletals 1a, 2b are connected smoothly and directly in the larger part thereof.
