PROBLEM TO BE SOLVED: To provide a method for manufacturing a capacitor formed by forming a dielectric film on at least one of the foil-shaped electrodes subjected to a surface-expansion treatment and winding the capacitor, the capacitor having excellent capacity achievement ratio and loss characteristics. Is intended to be easily obtained. SOLUTION: A conductive polymer layer is first formed on an electrode foil surface on which a dielectric layer is formed or on both electrode foil surfaces, and then wound, and further a conductive polymer or an electrolytic solution is formed in a gap between both electrodes. By forming the conductive layer described above, a capacitor having a high capacity achievement ratio and excellent in loss characteristics can be obtained. Further, according to the above configuration, the separator can be omitted at the time of winding, and furthermore, a conductive separator compounded with a conductive polymer can be used. can get. |
