An electric double-layer capacitor has a porous separator, a pair of polarizable electrodes confronting each other with the separator interposed therebetween, and an electrolytic solution, all accommodated in a gasket frame. The separator is electrically non-conductive and ion-permeable, and is impregnated with the electrolytic solution. The gasket frame has an opening sealed by a collector held against the surface of the polarizable electrode which faces away from the separator. The collector which seals the opening in the gasket frame comprises two laminated collector sheets. Since there is almost no possibility that both the two laminated collector sheets will crack or break, the electrolytic solution is reliably prevented from leaking out of the gasket.

1. An electric double-layer capacitor comprising:a porous, electrically non-conductive, ion-permeable separator impregnated with an electrolytic solution; a pair of polarizable electrodes disposed in confronting relation with the separator interposed therebetween; a gasket frame housing said separator and said pair of polarizable electrodes; and a lamination of at least two collector sheets held against a surface of said pair of polarizable electrodes facing away from said separator and attached to said gasket frame to seal said pair of polarizable electrodes and said separator within, wherein each of said laminated collector sheets is made of the same material and each of said laminated collector sheets is in direct contact with material over at least one common surface.
