Abstract

The electrical double layer capacitor includes a case, an electrolyte stored in the case, a positive electrode, a negative electrode, and a molecular sieve, wherein the electrolyte contains cation and anion, and the molecular sieve suppresses either one or both of the adsorption of cation onto a surface of the positive electrode and the adsorption of anion onto a surface of the negative electrode. Due to this configuration, it is possible to provide an electrical double layer capacitor having high withstand voltage and long life.
