ABSTRACT:
A hollow cylindrical resin case provided at a periphery thereof with an axial opening and a resin terminal plate, one of which has a concave coupling section and the other has a convex coupling section, are coupled together and then filler resin is injected between the capacitor element attached to the terminal plate and the resin case to provide a seal. One or both of the resin case and the resin terminal plate are made of thermoplastic resin, and a space is defined between the coupling sections. A dimension of the space and an inserting force applied to the coupling portions are set to appropriate values, thereby realizing a high quality capacitor free from leakage of filler resin.
