Abstract:
The purpose of the present invention is to provide a storage structure capable of maintaining a small size, light weight, moisture resistance, and pressure resistance in order to obtain a high-capacity capacitor having a plurality of capacitor elements using a metal film provided with vapor deposited metal electrodes on the surface of a dielectric film. A film capacitor is provided in which a plurality of capacitor elements comprising metallikon electrodes on both ends are accommodated in a cylindrical case and arranged in parallel, both ends of the cylindrical case being open. The capacitor elements are connected in parallel by external lead-out terminals. Both end portions of the cylindrical case are covered by a pair of concave terminal covers such that both end portions are covered together. The interior of the concave terminal covers is filled with an insulating resin. Notches or through-holes into which the insulating resin is filled are provided on at least one end surface of the cylindrical case.
