Abstract
A film capacitor includes: a film winding portion formed by winding at least one metalized film that includes a dielectric film and a metal film provided on a surface of the dielectric film; a pair of metallikon electrodes formed respectively on end faces of the film winding portion in a winding axis direction of the film winding portion; and a pair of busbars each of which is joined to a corresponding one of the metallikon electrodes via a joining metal. Each of the busbars is plate-shaped to cover an outer surface of the corresponding metallikon electrode. At least one of the metallikon electrodes has a ridge that is formed on the outer surface of the metallikon electrode to be convex in the winding axis direction toward the corresponding busbar. In the corresponding busbar, there is formed a ridge-receiving portion in which the ridge of the metallikon electrode is received.
