<p>PROBLEM TO BE SOLVED: To provide an exhaust particulate removing device without requiring acquisition of exhaust particulate included in exhaust gas discharged from a diesel engine and others by a resistance heating type filter element and the switching of an introducing path of exhaust gas by a valve at the subsequent combustion removal. SOLUTION: A plurality of resistance heating type filter elements 4 are loaded into a common cylindrical case 3 loadable in series, electric wiring 13 is performed so that resistance heating may be performed for porous metal sheets laminated in each resistance heating type filter element 4 and every resistance heating type filter element 4 can be individually energized. The resistance heating type filter element 4 is made by interposing a porous electric insulating film between opposed faces of the porous metal sheets 21. The porous metal sheets 21 are made by punching many through holes having rupturelike projections at peripheral ends in metal sheet materials.</p> |
