PROBLEM TO BE SOLVED: To provide a technology capable of manufacturing an inexpensive all-solid battery having excellent performance in high productivity. SOLUTION: A negative-electrode active material layer having an uneven pattern is formed on a surface of a copper foil as a negative-electrode current collector by applying application liquid by a nozzle-scan coating method (a step S102). Subsequently, application liquid containing a polymer electrolyte material is applied by a spin coating method, thereby forming a solid electrolyte layer in conformity with the uneven pattern (a step S103). Subsequently, application liquid is applied by a doctor blade method, thereby forming a positive-electrode active material layer whose lower surface conforms to the unevenness and whose upper surface is substantially flat (a step S104). A thin and high-performance all-solid battery can be produced by laminating an aluminum foil as a positive-electrode current collector before the application liquid is cured.
