PROBLEM TO BE SOLVED: To provide a solid electrolytic capacitor which can be improved in ESR characteristics under a high-temperature atmosphere and ESR characteristics during reflow.SOLUTION: The solid electrolytic capacitor includes a dielectric oxide film formed on a surface of an anode body having an expanded layer, a first conductive polymer layer formed on the oxide film, a second conductive polymer layer formed on the first conductive polymer layer, and a cathode conductor layer formed on the second conductive polymer layer. A mixed solution obtained by dispersing a conductive polymer compound in a solution containing water, ethylene glycol, and a nitro compound is applied to the first conductive polymer layer and then is dried to form the second conductive polymer layer. |
