An electric double-layer capacitor comprising a case, electrolyte stored in the case, an anode, a cathode, and a molecular sieving unit, wherein electrolyte contains cation and anion, and the molecular sieving unit prevents one or both of the adsorption of cation to an anode surface and the adsorption of anion to a cathode surface. A double-layer capacitor high in withstand voltage and long in service life is offered by this arrangement. |
