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 soft magnetic material by uniformly heating the metal foils. A laminate obtained by laminating the metal foils made of amorphous soft magnetic material is held by a holding member such that adjacent metal foils can be separated from each other in a laminated direction of the laminate. By conveying either the holding member or magnets in a direction perpendicular to the laminated direction as a conveying direction such that the holding member and the magnets come close to each other, the adjacent metal foils are separated from each other with a magnetic force of the magnets. The separated metal foils are heated to crystalize the amorphous soft magnetic material of the metal foils into nano-crystal soft magnetic material. The same magnetic pole of the magnets aligns in the laminated direction.
