Abstract
An electric double layer capacitor includes a plurality of basic cells each including a pair of polarizing electrodes sandwiching therebetween a separator and impregnated with an electrolyte. The separator is made of unwoven fabric or porous film including polyolefine or fluorine based resin. The polarizing electrodes and the separator are bonded together in advance before stacking the basic cells to form a stacked cell structure. The bonding is performed by applying a thrust pressure to the polarizing electrodes sandwiching the separator, while heating at a temperature above a softening temperature of the polyolefine or fluorine based resin.
