To provide the roll-like metal carrier not melting the brazed part in a honeycomb body and the base metal in the vicinity of the brazed part, hardly reducing the oxidation resistant life of the base metal and moreover capable of preventing damage due to thermal stress of a sheet even when a misfire generates in an engine and the temperature in the central part of the metal carrier for a catalyst device rises.
The amorphous brazing filler metal 3 mainly composed of Ni is placed on one side end surface 4a of the honeycomb body 4 formed by superposing the corrugated sheets 1 of ferritic stainless containing Al and flat sheets 2, the brazing filler metal is heated to melt, and the end parts of sheets are joined to form the metal carrier 10. The brazing filler metal is made to flow up to about 5mm from the end surface 4a by capillary phenomina to join the contacting part of both sheets.
