Abstract
An electric double layer capacitor with a control circuit component. When the electric double layer capacitor is provided in plural and these capacitors are serially connected for charging thereof through a source of DC power, the control circuit component balances charge Voltage of each electric double layer capacitor. The control circuit component is mounted to a control circuit board. The control circuit board has a diameter smaller than that of a sheath can of the electric double layer capacitor and is fixedly secured to a cover such that it does not project upwardly beyond an upper end of a pole projection, serving as a positive electrode, of the electric double layer capacitor.
