Abstract
An electric double-layer capacitor includes a cylindrical case having a bottom, a side surface, and an opening, a capacitor element accommodated in the case, the capacitor element, a driving electrolyte accommodated in the case, and a terminal plate provided at the opening of the case. The capacitor element includes a first electrode and a second electrode extending in a direction opposite to the first electrode. The second electrode is joined to the bottom of the case. The first and second electrodes are tilted away from the center axis of the capacitor element. In this electric double-layer capacitor, electrodes of the capacitor element are connected to the case and sealing plate reliably.
