Capacitor module

A capacitor body is laterally contained in a lower holder, to be then pressed by an upper holder. A lead wire is led from the capacitor body in an axial direction, and then, bent toward a wiring board, thereby forming a leg soldered to the wiring board. The lower holder includes a first holding portion extending outward and having a supporter disposed in a stationary state whereas the upper holder includes a second holding portion extending outward and having a bridge stretched between a pair of elastically deformable arms. The first and second holding portions are urged toward the capacitor body, and therefore, axially hold a part of the leg of the lead wire. This configuration can prevent any breakage of a soldered portion of the lead wire due to vibrations so as to enhance vibration resistance.
