PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrolyte membrane, capable of achieving both of shortening time of hydrolysis treatment which is performed on electrolyte membrane precursor film and suppressing the scattering of an alkaline aqueous solution.SOLUTION: A method of manufacturing an electrolyte membrane includes the steps of: arranging a conveyance roller R22 for conveying a thin film FL capable of being added ion conductivity by hydrolysis in an alkali aqueous solution less than 100°C; raising the temperature of the conveyance roller R22 to 100-250°C; and conveying the thin film FL by crawling over the conveyance roller R22.SELECTED DRAWING: Figure 4 |
