PROBLEM TO BE SOLVED: To provide a manufacturing method of a polymer electrolyte membrane with excellent properties such as simpleness and flatness.SOLUTION: A manufacturing method of a polymer electrolyte membrane comprises: A) a step of casting an organic solution of the polymer electrolyte onto a base material; B) a step of producing a polymer electrolyte membrane on the base material by evaporating an organic solvent in the organic solution of the polymer electrolyte casted on the base material in the A) step; C) a step of immersing the polymer electrolyte membrane produced on the base material in the B) step in a liquid in which the organic solvent is soluble without peeling the polymer electrolyte membrane from the base material; and D) a step of evaporating the liquid in which the organic solvent is soluble from the polymer electrolyte membrane after the C) step. |
