Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the cleaning performance by using a metal honeycomb carrier. SOLUTION: The metal honeycomb carrier 11 is formed by superposing a corrugated sheet 16 on a flat sheet 15 or winding the superposed corrugated sheet 16 and flat sheet 15 several times in order to support a catalyst component 38. A hole 21 having the inside diameter larger than 1/2 of a pitch of the corrugated sheet 16 is opened on the side surface of the metal honeycomb carrier 11 by using a laser beam. The corrugated sheet 16 and the flat sheet 15 are melted to form molten particles 36. A plurality of exhaust gas flow passages 31 to be formed by the corrugated sheet 16 and the flat sheet 15 are communicated with one another by the hole 21. COPYRIGHT: (C)2009,JPO&INPIT
