Abstract
An electrochemical capacitor is provided, including an organic electrolyte solution and polarized electrodes immersed in the organic electrolyte solution. As an active substance of the polarized electrodes, the reaction product of an electrochemical reaction of a partially oxidized carbon material that contains fine crystals of graphite-like carbon in an organic electrolyte solution is used. The electrochemical capacitor has a high electrostatic capacity density based on a pseudo-capacity.
