An electric double-layer capacitor comprising, as the positive electrode and the negative electrode, a material obtained by adhering a polarizable electrode on one or both sides of a conductive material by the use of a conductive adhesive, in which capacitor the polarizable electrodes are formed by a carbon material composed mainly of active carbon, amorphous carbon and expanded graphite, or the conductive adhesive is composed mainly of a resin and expanded graphite, or the polarizable electrodes are formed by a carbon material composed mainly of active carbon, amorphous carbon and expanded graphite and the conductive adhesive is composed mainly of a resin and expanded graphite. Said electric double-layer capacitor has alleviated the drawbacks of the prior art, has a low internal resistance, gives substantially no change in internal resistance when subjected to repeated discharging, and has a long life. |
