Abstract
A thin-type electric double layer capacitor having low internal resistance. This capacitor includes pairs of a current collector and polarizable electrode disposed opposite to each other with a separator being interposed therebetween. The current collector and polarizable electrode, each containing a thermoplastic binder resin and carbon, are made integral by compatibilization of the thermoplastic binder resins. Polarizable electrode faring with the separator is disposed on the plane as that for the current collector. In this capacitor, the glass-transition temperature of the thermoplastic binder resin contained in the current collector is lower than that of the thermoplastic binder resin contained in the polarizable electrode.
