The present invention provides a polymeric compound for a conductive polymer having a sulfo group of a specific strong acid, which is soluble in an organic solvent and is suitably used as a dopant for a fuel cell or a conductive material. The present invention is a polymer for a conductive polymer comprising at least one repeating unit a represented by the following formula (1), which is synthesized by ion exchange of a lithium salt, a sodium salt, a potassium salt or a nitrogen compound salt of a sulfonic acid residue, Wherein the weight average molecular weight is in the range of 1,000 to 500,000. |
