A polymer compound for a conductive polymer including one or more repeating units represented by general formula (1), which has been synthesized by ion-exchange of a lithium salt, sodium salt, potassium salt, or nitrogen compound salt of a sulfonic acid residue, and has a weight average molecular weight in the range of 1,000 to 500,000, wherein R1 represents a hydrogen atom or methyl group, R2 represents a single bond, an ester group, or a linear, branched, or cyclic hydrocarbon group having 1 to 12 carbon atoms which may have either or both of an ether group and an ester group, and Z represents a phenylene group, naphthylene group, or ester group. There can be provided a polymer compound for a conductive polymer having a specific super strongly acidic sulfo group, which is soluble in an organic solvent, and suitably used for a fuel cell or dopant for a conductive material.
