Abstract:
A process for manufacturing an electric double-layer capacitor, including the steps of inserting an electrolyte and an electrode group assembled from a current collector electrode, an electrode and a separator into a case and sealing the case,said process comprising the characteristic steps of: (i) using, as the separator, a fiber sheet comprising a fiber having fibrils and formed from a resin having a melting or carbonizing temperature of not lower than 300Â° C. and a fine fiber having a fineness of not more than 0.45 dtex (decitex) and formed from a resin having a softening temperature of not lower than 200Â° C. and, (ii) after assembling of the electrode group, drying the current collector electrode, the electrode and the separator at the temperature which is lower than the softening temperature of a resin having the lowest softening temperature among the constituent resins for the fibers comprised in the separator but not lower than the boiling point of water.
