Polymer compound for conductive polymer and method for producing same

A method for producing a polymer compound for a conductive polymer, the method comprises

• subjecting to polymerization reaction a monomer having a structure of a salt comprising a sulfonamide group bonded to a carbonyl group and lithium, sodium, potassium, or a nitrogen compound, and after the polymerization, changing the structure of the salt by ion exchange to a sulfonamide group bonded to a carbonyl group to produce a polymer compound containing a repeating unit represented by the following general formula (1),
• wherein, R1 represents a hydrogen atom or a methyl group;
• Rf1 represents a linear or branched alkyl group having 1 to 4 carbon atoms or a phenyl group, and has at least one fluorine atom or a trifluoromethyl group in Rf1;
• Z1 represents a single bond, an arylene group having 6 to 12 carbon atoms or —C(═O)—O—R2—;
• R2 represents a linear, branched or cyclic alkylene group having 1 to 12 carbon atoms, an arylene group having 6 to 10 carbon atoms or an alkenylene group having 2 to 10 carbon atoms, and may have an ether group, a carbonyl group or an ester group in R2;
• and “a” is 0<a≤1.0.
