An object of the present invention is to provide a polymer compound for a conductive polymer which is soluble in an organic solvent and which is suitable for use as a fuel cell or a dopant for a conductive material, and which has a sulfo group having a specific super acid. The solution is a polymer compound for a conductive polymer, which contains one or more polymer compounds for a conductive polymer having a repeating unit a represented by the following formula (1), and is characterized in that the weight average molecular weight is The range of 1,000 to 500,000. □ (wherein R1 is a hydrogen atom or a methyl group, and R2 is a single bond, an ester group, or a linear one having an ether group or an ester group or both of which have a carbon number of 1 to 12, Any of a branched or cyclic hydrocarbon group. Z is any one of a single bond, a phenylene group, a stretchy naphthyl group, an ether group, and an ester group. a is 0 < a ≦ 1.0). |
