Claims

[Scope of utility model registration request]

A cylinder chamber is formed between the inner wall and the outer wall by making the circumferential wall of the storage chamber double-layered, an opening facing the outside is formed at the lower end of the cylinder chamber, and a through hole leading to the storage chamber toward the inner wall is formed at the upper end. One or more wound capacitor elements are accommodated in the accommodation chamber of the formed container, facing both ends of each winding, with separate gaps provided for each, and an insulating gas is supplied into the accommodation chamber and the cylinder chamber. At the same time as filling the container, when molding the container with synthetic resin, the synthetic resin flows into the cylinder chamber and pressurizes it, sealing the insulating gas in the storage chamber to a positive pressure state and molding it to form a container-housed capacitor. 1. A high-voltage capacitor comprising: a plurality of container-housed capacitors, and the assembly is integrally molded around the assembly with the same synthetic resin as the synthetic resin or a different synthetic resin.
