Abstract:
A particulate material removing filter for exhaust gas from a diesel engine is provided. The particulate material removing filter is formed by laminating metal laths having an oxidation catalyst layer containing a noble metal that oxidizes nitrogen oxide in exhaust gas into nitrogen dioxide. The metal laths are laminated to form a laminate in such a manner that the drawing direction of the metal lath processing differs by 90 degrees with each other.
