In the figure, reference numeral 1 denotes a polarizable electrode in which a polarizable electrode material such as graphite, activated carbon, carbon black, etc. is supported along with some binder on a current collecting plate made of a metal with a valve function such as aluminum, tantalum, titanium, etc. , 2 is a microporous separator impregnated with an electrolytic solution, and 3 is an insulating back case and a spout plate, which also serve as external connection terminals. When this electric double layer capacitor is used for the memory backup, a capacitance of about 0.01 to 1 F is required at a working voltage of 5 cm, and in order to increase the withstand voltage, series connection by lamination is performed. It will be done. This lamination requires three partial row connections for a non-aqueous FIT M liquid with high AT pressure resistance, and six to seven partial connections for an aqueous electrolyte.
