ELECTRIC DOUBLE-LAYER CAPACITOR, STORAGE BATTERY PROVIDED WITH IT AND PRODUCTION METHOD FOR ELECTRIC DOUBLE-LAYER CAPACITOR

摘要

The sealing feature of the interior of an enclosure housing an electric double-layer capacitor body is improved. A chemical-resisting and thermoplastic synthetic resin sheet (40) is fusion-deposited over the entire periphery of the joint portion (30-1),with the inner-side surfaces of a positive-side opening (16-3), of a positive-side terminal electrode (30), and a chemical-resisting and thermoplastic synthetic resin sheet (42) is fusion-deposited over the entire periphery of the joint portion (32-1), with the inner-side surfaces of a negative-side opening (16-4), of a negative-side terminal electrode (32). Then, the sheet (40) and the inner-side surfaces of the positive-side opening (16-3) are fusion-deposited over the entire peripheries, and the sheet (42) and the inner-side surfaces of the negative-side opening (16-4) are fusion-deposited over the entire peripheries.
