1. A film capacitor comprising:
a stack including at least one dielectric film and a plurality of metal films, the at least one dielectric film including a polyarylate film, wherein each of the at least one of dielectric film and each of the plurality of metal films are alternately stacked in a stacking direction, each of the plurality of metal films deposited on each of the at least one dielectric film by vapor deposition;
cover films on two first side surfaces, the two first side surfaces facing each other in a first direction, the first direction orthogonal to the stacking direction, the cover films comprising a polyester hot-melt resin; and
metal-sprayed electrodes on two second side surfaces, the two second side surfaces facing each other in a second direction, the second direction perpendicular to the first direction and orthogonal to the stacking direction.
