A method of producing an electrolyte membrane-electrode assembly that constitutes a fuel cell includes a step of preparing a polymer electrolyte membrane formed of a solid polymer electrolyte, a step of forming a pair of electrodes each including a catalyst, on the polymer electrolyte, a step of preparing a cerium-containing film or films containing a cerium compound, and a step of superimposing the cerium-containing film(s) on the polymer electrolyte membrane on which the electrodes are formed, such that the cerium-containing film and the corresponding electrode are in contact with each other.
