Disclosed is a coating film which has high conductivity and prevents deterioration of conductivity when irradiated with ultraviolet light, even though a conjugated conductive polymer is dissolved in a solvent by a solubilized polymer. Provided is a conductive polymer solution capable of forming The conductive polymer solution of the present invention contains a π-conjugated conductive polymer, a solubilized polymer, a benzophenone compound represented by the following chemical formula (1), and a solvent. And (In the chemical formula (1), m and n are each independently an integer of 0 to 5, and m + n is 2 or more. The hydrogen atom of the benzene ring in the chemical formula (1) may be substituted with a substituent. Good.) [Chemical 1] [Selection figure] None |
