In this case, the layer film 3 uses a plurality of films with different widths, and changes from a wide film to a narrow film in the middle of the lamination of the coil layers 2. Therefore, the layer of the layer film 3 had a stepped portion 3a. The figure shows an example of two stages.

中する箇所が生じなくなり、電界が均一化される。[Function] In this way, as the width of the coil layer becomes narrower, by cutting the layer film width narrower and supplying it to the surface of the coil layer, the outer shape of the layer film does not become discontinuous but changes continuously. It becomes like this. Therefore, there are no locations where the electric field is concentrated, and the electric field is made uniform.
