Claims

[Scope of utility model registration request]

When molding the synthetic resin sealing body that closes the opening of the case in which the capacitor element is housed, a synthetic resin material is poured around the electrode terminal member to integrally form the electrode terminal member and the sealing body. In the sealing structure of an electrolytic capacitor, a sealing elastic body is attached in advance to the outer periphery of the electrode terminal member, and the sealing elastic body is sealed by the filling pressure of the synthetic resin material placed around the electrode terminal member. A sealing structure for an electrolytic capacitor characterized by crushing the body to seal between an electrode terminal member and a sealing body.
