1. A method for producing a solid-state battery, the method comprising:
laminating a solid electrolyte layer on a release sheet;
preparing a current collector layer, and an electrode stack that is formed by laminating active material layers on a front and a back of the current collector layer;
laminating the electrode stack on the solid electrolyte layer on one half side of the solid electrolyte layer so that one end of the electrode stack protrudes from an end of the solid electrolyte layer, and another end of the electrode stack is arranged on a center position of the solid electrolyte layer; and
folding the release sheet and a material of the solid electrolyte layer so as to form a valley along a center line of the solid electrolyte layer to cover, over the electrode stack, another half side of the solid electrolyte layer where the electrode stack is not laminated, so that the electrode stack is sandwiched by the solid electrolyte layer, wherein
the electrode stack except a protruding portion thereof is covered with the solid electrolyte layer.
