Abstract
An electric double layer capacitor has a pair of polarized electrodes in the form of electrode bodies each comprising a porous sintered body, and a pair of current collectors for collecting electric charges stored in the polarized electrodes, the current collectors being in the form of electrically conductive films. The electrically conductive films have surfaces dissolved by a solvent and joined to the electrode bodies with dissolved portions of the electrically conductive films being present in pores of the electrode bodies. The polarized electrodes and the current collectors are held in stable contact with each other, with a reduced contact resistance therebetween. The electric double layer capacitor thus has a small internal resistance.
