PROBLEM TO BE SOLVED: To provide an electric double layer capacitor having high capacity and low resistance. SOLUTION: The electric double layer capacitor includes: a laminated electric double layer capacitor cell which includes first and second electrodes arranged to face each other and an ion-permeable separator formed therebetween; and an insulating tape which encloses an outer surface of the laminated electric double layer capacitor cell and has a plurality of voids. In the electric double layer capacitor, movements between the first and second electrodes and the separator are minimized, so that the area of the facing surfaces of the first and second electrodes increases. Accordingly, high electric capacity may be achieved. In addition, a movement path of an electrolyte is secured by the voids formed in the insulating tape, and thereby impregnation of the electrolyte into the electric double layer capacitor cell is performed smoothly.
