Abstract

An electric double layer capacitor having a rectangular cross-section for an excellent volumetric efficiency and a low internal resistance is disclosed. The capacitor comprises a plurality of sheet-like current collectors in one polarity and in the other polarity; the surfaces of the both collectors are formed into polarizable electrodes composed mainly of activated carbon with a binder; a plurality of separators interposed between the current collectors of the one polarity and those of the other polarity.
