摘要： A capacitor includes a capacitor element, a bus bar connected to an electrode of the capacitor element, a case housing the capacitor element, and a filling resin filled in the case. The bus bar includes a first section and a second section. The first section is exposed from the filling resin and includes a connection terminal configured to be connected to an external terminal. The second section has a buried section buried in the filling resin and an exposed section exposed from the filling resin, and includes a connection part connected to the electrode. The exposed section is located away from the first section.

摘要： A film capacitor includes: a capacitor element in which a metallikon electrode is formed at an end; a bus bar connected with the metallikon electrode; a case having a container for housing the capacitor element and the bus bar; a lid member which covers an opening of the container; and a heat conducting member disposed between the bus bar and the lid member. The lid member has a protrusion on a side facing the heat conducting member, the protrusion is in contact with the heat conducting member, and the heat conducting member is in contact with the bus bar.

摘要： Film capacitor includes capacitor unit that has capacitor elements, upper bus bar, and lower bus bar. Capacitor elements have upper end electrodes and lower end electrodes that are connected to upper bus bar and lower bus bar, respectively. Film capacitor further includes case containing capacitor unit and being filled with filler resin, cooling plate near capacitor unit, and plate springs. Cooling plate is connected to a cooler and discharges heat generated from capacitor elements into the cooler. Plate springs apply an elastic force to capacitor unit in a direction toward cooling plate.
