PROBLEM TO BE SOLVED: To reduce the inductance of a circuit and to reduce the current imbalance of a capacitor cell.SOLUTION: In a capacitor unit including a plurality of capacitor cells, one surface of the capacitor unit is provided with a first positive electrode terminal and a negative electrode terminal and the other surface is provided with a second positive electrode terminal and a second negative electrode terminal which are different from the first terminals. By connecting the negative terminal of the capacitor cell to the second negative electrode terminal when the positive terminal of the capacitor cell is connected to the first positive electrode terminal, and by connecting the negative terminal of the capacitor cell to the first negative electrode terminal when the positive terminal of the capacitor cell is connected to the second positive electrode terminal, variations in the impedance of the wiring of each capacitor cell are reduced and the current imbalance of the capacitor cell is reduced. By arranging the electrodes of the adjacent capacitor cells so that they are different from each other, the inductance of the wiring in the capacitor unit is reduced.SELECTED DRAWING: Figure 4 |
