PURPOSE:To control the generation of imperfect parts, by laminating and winding a corrugated sheet and a flat sheet while the thermoplastic resin in a brazing material is melted, and temporarily fixing the sheet by the thermoplastic resin in the brazing material to form a compact. CONSTITUTION:The thin sheet of an iron-chromium-aluminum alloy is used for the corrugated sheet 2 and the flat sheet 1. The brazing material is prepared, for example, by using 40wt% Ni-Cr alloy and 60wt% thermoplastic polyethylene resin, melting the mixture to uniformly disperse the components, and then cooling and curing the material. The brazing material is packed in an inside coating machine 4 and an outside coating machine 3. The tip of the coating machine is heated by a heater 4 to melt the material, the melt is extruded from a nozzle 5, and the melt is coated in portions of a specified amt. on the tops of the corrugated sheet 2 on both sides. The thermoplastic resin coated on the corrugated sheet 2 is cured before being brought into contact with the flat sheet 1, and stuck to the top as shown by 8.
