PROBLEM TO BE SOLVED: To provide a method for manufacturing an all-solid battery, by which the strength of an outer peripheral portion of an electrode layer can be increased in a simple and convenient way without worsening a battery performance.SOLUTION: A method for manufacturing an all-solid battery including a positive electrode layer, a negative electrode layer, a solid electrolytic layer disposed between the positive and negative electrode layers, a positive electrode current collector layer disposed in contact with positive electrode layer, and a negative electrode current collector layer disposed in contact with the negative electrode layer, provided that the positive and negative electrode layers each includes an active material, and at least one of the positive and negative electrode layers is an electrode layer including a sulfide-based solid electrolyte comprises the steps of: cutting off, from a surrounding atmosphere, at least a center portion of each of first and second main surfaces of the at least one electrode layer including the sulfide-based solid electrolyte; and exposing the at least one electrode layer to an atmosphere having a dew point temperature of -30°C or higher in the cutoff state. |
