Zusammenfassung:An insulating element includes a first coil; a second coil; and an inter-layer insulating film located between the first coil and the second coil. The inter-layer insulating film includes a first layer, a second layer, and a third layer located between the first layer and the second layer. The first layer is located between the first coil and the third layer. The second layer is located between the second coil and the third layer. A bandgap of the third layer is narrower than a bandgap of the first layer and a bandgap of the second layer.
