Abstract

PURPOSE:To manufacture the cut core easily, and to improve reluctance by a method wherein a wound body is manufactured by winding an amorphous magnetic alloy metallic plate on a bobbin in nonmagnetic metal, the wound body is cut to a desired shape, a bobbin metallic section of the wound body is fastened, and the bobbin is cut to a desired shape. CONSTITUTION:When manufacturing the cut core of an amorphous magnetic alloy thin-plate magnetic core, effective permeability thereof is 500 or higher, collar-shaped guide sections 3, 3' are integrally formed together with a winding section 2, caulking pawls 4, 4' are shaped at the noses of the guide sections 3, 3', and the nonmagnetic bobbin is prepared. The amorphous magnetic alloy thin-plate 5 is wound on the bobbin, an outer side surface of the thin-place 5 is pressure-welded and fixed by means of the caulking pawls 4, 4', and the wound body 1 is formed. When the wound bodies 1 are cut to the desired shape, the bobbin metallic sections of two or more of cut bodies 7, 7' are fastened or the bobbin metallic sections of two or more of the wound bodies 1 are fastened. The bobbin is cut to the desired shape, the cut core 9 with the desired shape is easily manufactured, and reluctance is improved.
