    • A through capacitor which includes a generally cylindrical inner electrode having a through hole through which a lead terminal extends. The lead terminal has a protuberance adjacent to and axially outward of a first opening of the hole. A generally cylindrical outer electrode surrounds the inner electrode in radially spaced relation thereto. The lead terminal is fixed to the inner electrode with solder including a radially expanded portion of solder embedding the protuberance therein. The inner electrode is bent radially outwardly such that the through hole is tapered radially outwardly toward a second opening opposite the first opening to define an expanded space between the lead terminal and the inner electrode. Solder fills the expanded space so as to resist axial movement of the lead terminal through the through hole in the direction from the second opening toward the first opening.
