Abstract
A stacked film capacitor including a resin protective film having excellent durability is provided which can stably secure desired properties. The stacked film capacitor includes a capacitor element including a plurality of dielectric layers, and a plurality of vapor-deposited metal film layers. Each dielectric layer and each vapor-deposited metal film layer are stacked with each other so as to be arranged alternately. The stacked film capacitor further includes a pair of external electrodes provided on opposing side surfaces of the capacitor element, and at least one resin protective film formed on at least one side surfaces other than the side surfaces on which the external electrodes are formed, in which the at least one resin protective film is provided by deposition polymerization.
