PROBLEM TO BE SOLVED: To provide a manufacturing method for obtaining a membrane electrode assembly exerting greatly improved battery performance as compared with a prior art, through improvement of electric jointing between an electrolyte membrane containing polymer electrolyte having a hydrocarbon skeleton and an electrode. SOLUTION: After a process of either irradiating active energy beams under existence of oxygen on the surface of an electrolyte membrane containing a structure filled with polymer electrolyte, or exposing it to an atmosphere containing oxygen after irradiating at an atmosphere not containing oxygen, the electrolyte membrane and the electrode are jointed to manufacture the membrane electrode assembly.
