Abstract
A film capacitor includes a first film, a second film, a first electrode part, and a second electrode part. The first electrode part includes a first aluminum-containing layer disposed on a first film surface. The second electrode part includes a second aluminum-containing layer disposed on a second film surface. The first film and the second film stacked on one another are wound or stacked. The first film surface is provided with a first non-electrode part that does not include the first aluminum-containing layer and extends in the longitudinal direction of the first film surface. The first electrode part has a first end adjacent to the first non-electrode part. The second film surface is provided with a second non-electrode part that does not include the second aluminum-containing layer and extends in the longitudinal direction of the second film surface. The second electrode part has a second end adjacent to the second non-electrode part. A film capacitor further includes a first zinc-containing layer disposed on the surface of a part including the first end and a second zinc-containing layer disposed on the surface of a part including the second end.
