To provide a method for manufacturing an all-solid battery, which, even after the process of removing a binder for a sheet, allows a conductive assistant to remain in a coating layer without evaporating, resulting in causing no deterioration in electronic conductivity.SOLUTION: In a method for manufacturing an all-solid battery, a solid electrolyte and a conductive assistant are coated on an active material. In the method, after the conductive assistant is supported on a surface of the active material by subjecting the solid electrolyte to heat treatment, a sheet of an electrolyte layer and a sheet of an active material layer are laminated, pressed and fired.SELECTED DRAWING: Figure 2 【課題】シート用バインダーを脱バインダーする工程を経ても、導電助剤が蒸発することなくコーティング層内に残留し、電子伝導性の劣化がない全固体電池の製造方法を提供することを目的とする。【解決手段】固体電解質および導電助剤を、活物質にコーティングして製造する全固体電池の製造方法において、前記固体電解質を熱処理することによって前記導電助剤を前記活物質表面に担持させた後、電解質層および活物質層のシートを積層し、圧着し、焼成する、全固体電池の製造方法。【選択図】図２
