1. A conductive polymer solution having a conductive polymer and a solvent, whereinthe conductive polymer comprisesa pi-conjugated conductive polymer,a polyanion with which the pi-conjugated conductive polymer is doped, anda compound formed by reacting an oxirane or oxetane group which is needed to increase the strong acidity of a solution derived from the anion group of the polyanion to a weak acidic region of a pH in the range of 2.0 to 6.0 with an anion making no contribution to the dope in the polyanion, andthe solution has a pH in the range of 2.0 to 6.0.
