According to a method of manufacturing a membrane electrode assembly having an excellent electric power generating capability, a base 11 is coated with a first polymer electrolytic solution 12 to form a first polymer electrolytic membrane 12a which is undried. The undried first polymer electrolytic membrane 12a is coated with a first electrode dispersion 13, which comprises a second polymer electrolytic solution and a catalyst carried on a catalyst carrier and dissolved therein. The first electrode dispersion 13 is dried to form a first electrode 2a, thereby forming a positive-electrode membrane electrode assembly 14a. Another base 11 is coated with a third polymer electrolytic solution 12 to form a second polymer electrolytic membrane 12b which is undried. The undried second polymer electrolytic membrane 12b is coated with a second electrode dispersion 13, which comprises a fourth polymer electrolytic solution and a catalyst carried on a catalyst carrier and dissolved therein. The second electrode dispersion 13 is dried to form a second electrode 2a, thereby forming a negative-electrode membrane electrode assembly 14b. The membrane electrode assemblies 14a, 14b are integrally combined with each other by joining said first and second polymer electrolytic membranes 12a, 12b with a fifth polymer electrolytic solution 15 interposed therebetween.
