It is desirable to operate with a pressure of 0 kg/m2 applied to the electric double layer capacitor and maintained therein. Conventionally, this type of electric double layer capacitor can be obtained by stacking the required number of electric double layer capacitors (hereinafter referred to as basic cells) as shown in Figure 1 (1m) to meet the t-required operating voltage.
