Abstract
An electric double layer capacitor employs a paste electrode between collector electrodes. The paste electrode is compressed under small load because the collector electrodes are pressed by compression plates in only an area corresponding to the past electrode. With the paste electrode thus compressed, the internal resistance of the capacitance is reduced and the capacitance of the capacitor is stable. The electric double layer capacitor comprises a stack of basic cells of capacitor elements. The basic cells are held closely together by a bolt which extends through central holes in the basic cells and interconnects the compression plates, so that the basic cells are compressed under a uniform and appropriate pressure.
