積層板コイル６を作る。As shown in Fig. 1, coils 1 and 2 each made of Al (aluminum) and Ti (titanium) that are ultra-thin plates of 0.1 mm or less are wound.
The coil 1 and the coil 2 are alternately arranged and rewound, and the ultrathin plate is washed through the surface cleaner 3 with the vapor of trichlorethylene to remove the oil and the like attached to the ultrathin plate. After polishing the surface, the cold rolling mill 4 presses and adheres six ultra-thin plates to form a laminated plate 5 composed of six metal layers, and the laminated plate 5 is wound on a reel and laminated.
