PROBLEM TO BE SOLVED: To provide a solid polymer electrolytic film/electrode joint body of superior conductivity and heat resistance, minimized in the load to environments in disposal by reducing the fluorine content, and usable for a solid polymer fuel cell, and to provide a manufacturing method thereof. SOLUTION: In this solid polymer electrolytic film/electrode joint body, formed of a solid polymer electrolytic film and electrode catalyst layers bonded to both sides thereof, the solid polymer electrolytic film and/or the electrode contain an ionic group-containing polybenzoxazole or ionic group-containing polybenzothiazole. |
