The purpose is to provide a technique which enables various kinds of conductive polymer composition to be dissolved in an organic solvent and to be used to form a conductive membrane on a target portion easily. Provided is a composite conductive polymer composition, a method of manufacturing the same, and a solution obtained by dissolving the composition in a alcohol-based, glycol-based, or ether-based solvent. The composition is obtained by doping a π-conjugated polymer (β) with a polymer compound (A), wherein the polymer compound (A) is obtained from (a-1) a monomer having a sulfonic acid group and a polymerizable vinyl group in an amount of 20 to 75 mol %, (a-2) a polar monomer having a hydrophilic group and a polymerizable vinyl group in an amount of 20 to 80 mol %, and (a-3) another polymerizable monomer in an amount of 0 to 20 mol %, and the π-conjugated polymer (β) is obtained from a monomer compound selected from the formulas (I) to (III) in the formula (I) to (III), at least one of R1 to R4 represent —OH or an alkoxy group of C1 to C6, and the other groups represent H, —OH, alkyl group of C1 to C4, or an alkoxy group of C1 to C6; at least one of R5 and R6 represent —OH or an alkoxy group of C1 to C6, and the other group represents H, —OH, an alkyl group of C1 to C4, or an alkoxy group of C1 to C6, or R5 and R6 jointly represent an alkylenedioxy group of C1 to C8; and R7 represents H, —OH, an alkyl group of C1 to C6 or an aromatic ring group.
