Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a proton conductive polymer electrolyte membrane (graft electrolyte membrane) in which a side chain having a proton conductive group is graft polymerized with a substrate, capable of achieving excellent joining with an electrode without setting a joining condition in forming a membrane electrode assembly (MEA) to be severe to the membrane.SOLUTION: The proton conductive polymer electrolyte membrane has a structure where a side chain having a proton conductive group is graft polymerized with a substrate comprising a vinylidene fluoride (VdF)-hexafluoropropylene (HFP) copolymer.
