Claims5
A capacitor module comprising:
- a capacitor element;
- a plurality of connection terminals for electrically connecting the capacitor element to other equipment;
- and
- an exterior coating that includes a resin film having electrical insulating property and wraps the capacitor element except the plurality of connection terminals, wherein
- the exterior coating is formed by joining a plurality of joining pieces constituting the resin film to all outer surfaces of the capacitor element so that the plurality of joining pieces butt each other when in an unfolded state, and
- the plurality of connection terminals are constituted to protrude through one of protrusion openings that are formed by notches provided in advance in at least one of the plurality of joining pieces when the plurality of joining pieces are butted, and protrusion openings provided in advance to penetrate at least one of the plurality of joining pieces, or protrude through only protrusion openings formed by notches provided in advance in at least one of the plurality of joining pieces when the plurality of joining pieces are butted.
