ABSTRACT:
A metal catalyst carrier has a core comprising a corrugated sheet and a flat sheet with a plurality of slots in a shape elongated in a direction perpendicular to a cell passage direction. The slots are formed before a sheet metal is corrugated and have a predetermined interval apart from one another. The plural slots disposed along the direction perpendicular to the cell passage direction are arranged to form a plurality of slot arrays arranged in the cell passage direction, and an interval Y in the cell passage direction and an interval X in the direction perpendicular to the cell passage direction, between the opening peripheral edge portions of the slots adjacent to each other in the slot arrays adjacent to each other, are set under the conditions satisfying X≧0 mm and X≧−(5/2)Y+10 mm, thereby preventing the occurrence of distortions and cracks in the process of corrugating the sheet metal.
