Abstract
A film capacitor includes a first film, a second film, a first electrode part, and a second electrode part. The first electrode part is disposed on a first film surface of the first film. The second electrode part is disposed on a second film surface of the first film or the second film. The first film surface has a first non-electrode part extending along a longitudinal direction of the first film surface. The second film surface has a second non-electrode part extending along a longitudinal direction of the second film surface. A first region having a light transmittance ranging from 30% to 80%, inclusive, is disposed between the first electrode part and the first non-electrode part. A second region having a light transmittance ranging from 30% to 80%, inclusive, is disposed between the second electrode part and the second non-electrode part. A width of each of the first region and the second region is less than or equal to 0.5 mm.
