Abstract:
1. A capacitor device comprising: a plurality of capacitor elements, each of which has a first terminal on one end side and a second terminal on the other end side in an axial direction, and which are plurally arranged along the axial direction and plurally arranged along a direction crossing the axial direction; an upper plate disposed so as to be joined to one end portion in the axial direction of each of the plurality of capacitor elements arranged along the axial direction; a lower plate disposed so as to be joined to the other end portion in the axial direction of each of the plurality of capacitor elements arranged along the axial direction; and an intermediate plate disposed between the capacitor elements adjacent to each other along the axial direction, wherein the capacitor elements adjacent to each other along the axial direction are electrically connected to each other by fitting between the first terminal of one capacitor element and the second terminal of the other capacitor element, the intermediate plate allows the terminals fitted to each other between the capacitor elements adjacent to each other along the axial direction to penetrate through and positions these capacitor elements, the upper plate is electrically connected to the first terminals or the second terminals of the capacitor elements arranged on one end portion in the axial direction, the lower plate is electrically connected to the first terminals or the second terminals of the capacitor elements arranged on the other end portion in the axial direction, and all of the plurality of capacitor elements are held in place by being sandwiched between the upper plate and the lower plate.
