Abstract

A dispersion liquid including one of thiophene and derivatives thereof, a polyanion, and a solvent is prepared. Then, the dispersion liquid is mixed with an oxidizing agent so as to oxidatively polymerize the one of thiophene and derivatives thereof. During the oxidative polymerization, a temperature of the dispersion liquid is 35° C. or less and a dissolved oxygen concentration of the dispersion liquid is 7 ppm or less.
