Beschreibung
Zusammenfassung:	A coating structure includes a base made of metal, a foundation layer provided on the base, and an insulation film provided on the foundation layer. The insulation film includes a plurality of layers, each layer of the plurality of layers being different in material, the plurality of layers being layered alternately with each other. The foundation layer is provided by a method other than a coating method using a surface chemical reaction occurring on the base, and a part of the foundation layer in contact with the base is amorphous. According to this, when a foreign material adheres on the base, the foreign material can be covered by the foundation layer. Since the insulation film is provided on the foundation layer, forming defects of the insulation film caused by the foreign material can be limited.
