Abstract: A film capacitor includes a first electrode layer, a second electrode layer, and a dielectric film disposed between the first and second electrode layers. The dielectric film mainly contains a styrene polymer having a syndiotactic structure. The first electrode layer includes first small electrode segments and a first fuse which interconnects the first small electrode segments. A value obtained by dividing an area of each of the plurality of first small electrode segments by the third power of a thickness of the dielectric film is not smaller than 0.4×1013/m and not larger than 5.0×1013/m. The film capacitor has a high withstanding voltage.
