The electric double layer capacitor has a case, an electrolytic solution housed in the case, a positive electrode, a negative electrode, and a molecular sieve part. The electrolytic solution contains a cation and an anion, and the molecular sieve part is on the positive electrode surface of the cation. One or both of the adsorption of the anion and the adsorption of the anion to the negative electrode surface are suppressed. With this configuration, an electric double layer capacitor having a high withstand voltage and a long life is provided. |
