Abstract: Provided is a method for manufacturing an all-solid-state battery which allows a solid electrolyte layer and an electrode to be in sufficiently close in contact with each other without deformation of the electrode shape or damages upon the electrode. The method for manufacturing an all-solid-state battery includes applying slurry for a solid electrolyte layer to the surface of an electrode active material layer to form a patterned solid electrolyte layer, and carrying out pressurization to form a solid electrolyte layer.
