PROBLEM TO BE SOLVED: To provide a conductive polymer solution which can obtain desired viscosity with less addition of a thickner than a prior art, and which can provide a conductive polymer having suppressed deterioration in conductivity.SOLUTION: The conductive polymer solution at least includes a conductive polymer, at least one of water and a water-miscible organic solvent, a dopant, and a thickner. The thickner comprises at least one kind of polymer having a carboxyl group and an electron-withdrawing functional group. The electron-withdrawing group is at least one kind selected from the group consisting of a ketone group, an ester group, an aldehyde group, a cyano group, a nitro group, an amino group, a hydroxyl group, and an ether group. |
