<p>PURPOSE: To have an opening hole part hardly closed, and collect fine particles on a sufficient surface area by forming a gas filter with a sheet shaped sintered body on which a plurality of penetrating holes are formed from an outside supplementally. CONSTITUTION: A filter which is formed of a sheet shaped sintered body 1 on which several penetrating holes 4 are formed from an outside supplementally is used as the filter which is formed in such constitution that sufficient surface area is obtained and also closing of the filter is hardly generated, in order to collect soot included in exhaust gas of an internal combustion engine and fine particle (particulate) of severalμm and less of hydrocarbon system. More preferably, the sheet shaped sintered bodies 1 are used by being laminated in a layer shape. Such a gas filter is manufactured in such a way that composition 2 including sintered powder and binder is formed in a sheet shape, a plurality of penetrating holes 4 are formed on the composition 2 by penetrating means 3 for forming the penetrating holes 4 on a surface, and then the composition 2 is sintered.</p> |
