摘要： A magnetic core comprises at least one layer of magnetic film composed of an amorphous alloy and an electrically insulating film made of polyimide. Powder materials having a property for alleviating mutual influence between the magnetic thin film and the insulating film during a heat treatment thereof are stuck to a surface of the magnetic film or the insulating film. The magnetic film and the electrically insulating film are alternately wound up in a predetermined shape with powder material interposed therebetween to thereby form a magnetic core.
