PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which can be profitably improved in electric capacitance. SOLUTION: This capacitor is provided with an anode fine hole retaining member that is possessed of fine holes and serves as a base material for an anode 1 which adsorbs negative ions, and a cathode fine hole retaining member that is possessed of fine holes and serves as a base material for a cathode 2 which adsorbs positive ions. At this point, the fine holes of the anode fine hole retaining member are set relatively larger in diameter than those of the cathode fine hole retaining member. |
