<p>PROBLEM TO BE SOLVED: To prevent breakage of a particulate filter, to remove ash from the particulate filter without burning, to simplify nonwoven fabric welding work to be carried out for stopping, to improve workability by making a laminated body easy to be put in a heat-resisting container, and to reduce the number of regenerating treatment to be carried out in the case when particulate matter such as soot is accumulated in the particulate filter. SOLUTION: The particulate filter 1 has a shaft core 7 made of heat resisting metal, the laminated body 3 formed by winding a laminated material made by laminating nonwoven fabric 11 and a corrugated sheet 13 made respectively of heat resisting metal around the shaft core and the metallic container 5 to load the laminated body 3.</p> |
