Claim Text:
1. A method of manufacturing a conductive polymer microparticle dispersion, the method comprising: preparing a polyanion which is at least one of polystyrene sulfonic acids and polystyrene sulfonates each having a Hazen color number in a range of 10 to 1000, inclusive, when a hue of a 2% aqueous solution thereof is measured by American Public Health Association method; preparing a dispersion liquid by dispersing, in a solvent mainly composed of water, at least one monomer selected from thiophenes and derivatives thereof, and the polyanion as a dopant; and preparing a conductive polythiophene microparticle dispersion doped with the polyanion by mixing the dispersion liquid with an oxidizing agent so as to oxidatively polymerize the at least one monomer.
