Abstract of the Disclosure A rolled core is formed by winding a thin body of an amorphous magnetic alloy having positive magnetostriction characteristics so that, of the two surfaces the surface of smaller surface coarseness faces inward. This rolled core is improved in iron loss over a rolled core obtained by winding the thin body so that the surface of greater surface coarseness faces inward. Breakage of the thin body tends to occur less frequently when it is wound so that the surface faces inward.
