ABSTRACT:
An electric double layer capacitor has an electric double layer composed of an interface between activated carbon and electrolyte. The electric double layer capacitor includes a pair of polarized electrodes each comprising an electrode body in the form of a porous sintered body of joined active carbon particles. When the electrode body is sintered, an electrically conductive layer is formed on a surface of the electrode body. With this construction, the contact resistance between the electrode body and a current collector through the electrically conductive layer is reduced, so that the electric double layer has a reduced internal resistance.
