Patent attributes
There is provided a method for producing metal foils, capable of easily crystalizing amorphous soft magnetic material of a plurality of metal foils into nano-crystal magnetic by uniformly heating the metal foils. Separating members (magnets) are disposed on the opposite sides of a laminate, which has been obtained by laminating a plurality of metal foils made of amorphous soft magnetic material, in the laminated direction of the laminate, and the metal foils forming the laminate are magnetized with the magnets. Thus, the adjacent metal foils are separated from each other in the laminated direction and a gap is formed between the metal foils. The metal foils are heated with the gap formed therebetween so that the amorphous soft magnetic material of each metal foil is crystalized into nano-crystal magnetic material.
