PROBLEM TO BE SOLVED: To provide a method for purifying aπ-conjugated conductive polymer which is applicable to an electrical energy storage device and a semiconductor device and excellent in heat resistance and moisture resistance by efficiently removing iron ions remaining in theπ-conjugated conductive polymer. SOLUTION: The method for purifying aπ-conjugated conductive polymer produced from a monomer as a raw material of theπ-conjugated conductive polymer by an oxidation polymerization reaction using an aromatic sulfonic acid metal salt as an oxidizing agent comprises, after the polymerization reaction, removing iron ions remaining in theπ-conjugated conductive polymer by cleaning theπ-conjugated conductive polymer with a cleaning solution which contains a specified chelate compound and whose concentration, temperature and pH are controlled. The resultingπ-conjugated conductive polymer is suitable as a material for composing an electrical energy storage device and a semiconductor device due to its excellent heat resistance and moisture resistance.
