Film capacitor, film for film capacitor, method of manufacturing film for film capacitor, and method of manufacturing film capacitor

摘要

A film capacitor of the present invention includes a resin layer having a linear protrusion on a first surface and having a linear recess on a second surface, and a metal layer provided on the first surface of the resin layer. In this film capacitor, in the second surface of the resin layer, a total length of the linear recess per 1 cmsup2/supis 3 m or less, and an average depth of the linear recess is 0.01 µm or more and 1.3 µm or less.
