Abstract
There is disclosed an electric double-layer capacitor that is adapted for use in an electric vehicle, for example, and uses aluminum collector electrodes. A native oxide film is formed on each aluminum electrode. Hard granular carbon is made to penetrate through the oxide film into each aluminum electrode. The aluminum electrodes are connected with positive and negative polarizing electrodes, respectively, via the granular carbon, thus lowering the contact resistance.
