The present invention provides a large electrostatic capacity, low ESR, and excellent long-term reliability without using conductive liquids for forming conductive polymer layers of different compositions or forming internal conductive polymer layers by different methods. A conductive polymer solution for a capacitor, the capacitor, and a method for manufacturing the same. The present invention relates to a conductive polymer solution, a capacitor including the conductive polymer solution or a compound obtained by removing a solvent from the solution, and impregnating the conductive polymer solution into the capacitor and removing the solvent. A method for manufacturing a capacitor, wherein the conductive polymer solution includes a conductive polymer and a solvent, and the conductive polymer includes a π-conjugated conductive polymer and a polymer doped with a π-conjugated conductive polymer. Among the anions and polyanions, compounds which do not contribute to the doping of the anions react with ethylene oxide or oxetanyl groups, and the pH of the solution is 2.0 or more and 6.0 or less. |
