PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode body in which breakage of a current collector foil during pressing can be suppressed using an electrode body in which a negative electrode mixture and a positive electrode mixture with respect to a negative electrode current collector foil and a positive electrode current collector foil are installed on both surfaces.SOLUTION: In a method of manufacturing an electrode body, when a positive electrode having a positive electrode layer and a solid electrolyte layer on both surfaces of a positive electrode current collector foil, and a negative electrode having a negative layer and the solid electrolyte layer on both surfaces of a negative electrode current collector foil and a size larger than that of the positive electrode are laminated on each other, the displacement amount of film thickness prevented from generating breakage of a current collector foil is obtained in advance by measuring the film thickness of a press part to which pressing pressure is applied and the film thickness of a non-press part which is not laminated on the positive electrode and to which the pressing pressure is not applied, and the positive electrode and the negative electrode are pressed and laminated by the pressing pressure based on the displacement amount of the film thickness. |
