(57) [Abstract] [PROBLEMS] To form electrolyte layers of various shapes without impairing productivity. SOLUTION: When forming an electrolyte layer 8 having at least an electrolyte salt, a swelling solvent and a matrix polymer on an electrode 21, the electrolyte salt, the swelling solvent and the matrix polymer are dissolved in a solvent to form an electrolyte solution. Is prepared, a first step of heating the electrolyte solution, a second step of spraying the electrolyte solution on the electrode 21 with heated air, and a solvent in the electrolyte solution sprayed on the electrode 21 And removing the electrolyte layer 8 to form a third step. |
