摘要： 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.

摘要： Disclosed herein is a planar magnetic element comprising a substrate, a first magnetic layer arranged over the substrate, a first insulation layer arranged over the first magnetic layer, a planer coil formed of a conductor, having a plurality of turns, arranged over the first insulation layer and having a gap aspect ratio of at least 1, the gap aspect ratio being the ratio of the thickness of the conductor to the gap between any adjacent two of the turns, a second insulation layer arranged over the planar coil, and a second magnetic layer arranged over the second insulation layer. When used as an inductor, the planar magnetic element has a great quality coefficient Q. When used as a transformer, it has a large gain and a high voltage ratio. Since the element is small and thin, it is suitable for use in an integrated circuit, and can greatly contribute to miniaturization of electronic devices.

摘要： Disclosed is a planar inductor which has spiral conductor coil means sandwiched between ferromagnetic layers with insulating layers interposed therebetween. The spiral conductor coil means is formed of two spiral conductor coils of the same shape arranged flush with and close to each other. Moreover, the two spiral conductor coils are connected electrically to each other so that currents of different directions flow individually through the conductor coils. Furthermore, the spiral conductor coil means is sandwiched between the two ferromagnetic layers with the insulating layers therebetween, each of the ferromagnetic layers having an area greater than the combined area of the two conductor coils. In the planar inductor according to the present invention, inductance is prevented from lowering while its components are being bonded together, so that the inductance value per unit volume is increased.
