PROBLEM TO BE SOLVED: To reduce ESR of an electrolytic capacitor.SOLUTION: A method for manufacturing a conductive polymer fine-particle dispersoid includes preparing a fluid dispersion containing a monomer having a &pgr;-conjugated structure, polyanion, and a solvent. The polyanion when the monomer is then subjected to oxidation polymerization contains at least one of polystyrene sulfonate and a salt thereof in which the color tone of a solution obtained by dissolving the polyanion in water so as to have a concentration of 2% is not less than 10 nor more than 1000 in Hazen color number measured by APHA method. |
