ABSTRACT:
This invention concerns an electric doublelayer capacitor composed essentially of one or more than one cells piled up one after another, a plus terminal plate with a plus terminal rod put beneath the lowermost cell, an insulating plate, a minus terminal plate with a minus terminal rod put beneath the insulating plate, an insulating tube surrounding the cells and a casing covering the top, side and lowermost periphery of all the above united components, which is made of a shrinkable electroconductive resin film. The film, electrically connecting the upper surface electrode of the uppermost cell to the minus terminal plate, is used to seal up all the united components air-tight by making use of its heat-shrinkability; therefore, the sealedness of the capacitor and the contactness of individual cells are improved very much, compared with conventional double-capacitor of this type employing metal casing, which naturally results in the increase of water- and solvent-proofness.
