Abstract
A film capacitor that includes a resin layer which has a first surface and a second surface and in which there are particles on at least one of the first surface and the second surface; and a metal layer on the first surface of the resin layer, wherein there are more particles in number on the at least one of the first surface and the second surface of the resin layer than inside the resin layer.
Claims10
A film capacitor comprising:
- a resin layer which has a first surface and a second surface and in which there are particles on at least one of the first surface and the second surface;
- and
- a metal layer in direct contact with the first surface of the resin layer,
- wherein there are more particles in number on the at least one of the first surface and the second surface of the resin layer than inside the resin layer, and there are no particles inside the resin layer.

A method for manufacturing a film-capacitor film, the method comprising:
- attaching particles to a resin-solution-coating surface of a base material film;
- forming a resin layer by coating the resin-solution-coating surface of the base material film with a resin solution;
- transferring the particles from the resin-solution-coating surface of the base material film to a surface of the resin layer by peeling the resin layer off the base material film such that there are more particles in number on the surface of the resin layer than inside the resin layer, and there are no particles inside the resin layer;
- and
- forming a metal layer directly on the surface of the resin layer.
