ABSTRACT:
A capacitor device is provided which includes a plurality of electric double-layer capacitors connected in series, and a balance resistor portion where five resistors having an equivalent resistance are connected in parallel. In this capacitor device, the balance resistor portion is connected to each electric double-layer capacitor, so that the electric double-layer capacitors connected in series can be charged uniformly.
