PROBLEM TO BE SOLVED: To provide a membrane-electrode structure for a solid polymer fuel cell insoluble to hot water while having a high proton acid group concentration capable of obtaining high proton conductivity and a highly wet state, and yet equipped with a polymer electrolyte film with excellent dimensional stability. SOLUTION: The membrane-electrode structure for a solid polymer fuel cell is to be provided with a solid polymer electrolyte film containing a polymer having a cross-linking structure obtained from a mixture solution including a polymer electrolyte containing a proton acid group, a compound containing a plurality of alcoholic hydroxyl groups and a solvent.
