PROBLEM TO BE SOLVED: To provide a capacitor provided with a conductive layer composed of a polythiophene derivative, which is excellent in stability under high temperature and high humidity, and a method of manufacturing the same. SOLUTION: A pair of electrodes are provided facing the dielectric layer, At least one of the electrodes has a benzenesulfonic acid ion having at least one sulfonic acid group, an alkylbenzenesulfonic acid ion having at least one alkyl group and a sulfonic acid group, or a naphthalenesulfonic acid ion having at least one sulfonic acid group. A polythiophene derivative doped with at least one of them and at least one of alkylnaphthalenesulfonate ions having at least one alkyl group and a sulfonic acid group, or at least one anthraquinonesulfonate ion having at least one sulfonic acid group And a method for manufacturing the same. |
