Claim:
1. A method for producing an all-solid-state battery, comprising the steps of: (A) disposing a first electrode active material layer containing a first electrode active material on both sides of a first collector having a first main surface and a second main surface, to form a first electrode layer, (B) disposing a solid electrolyte layer containing a solid electrolyte on each of the first electrode active material layers disposed on both sides, (C) disposing a second electrode active material layer containing a second electrode active material, and a second collector, on the solid electrolyte layers disposed on each of the first electrode active material layers, in such a manner that the second electrode active material layers contact with the solid electrolyte layers, (D) pressing a stack comprising the second collector, second electrode active material layer, solid electrolyte layer, first electrode active material layer, first collector, first electrode active material layer, solid electrolyte layer, second electrode active material layer and second collector, formed in steps (A) to (C), to form a battery unit at a pressing pressure of 50 to 1000 MPa, (E) repeating steps (A) to (D) to form a plurality of battery units, and (F) stacking the plurality of battery units, wherein, when the first electrode active material layer is a positive electrode active material layer, the second electrode active material layer is a negative electrode active material layer, and when the first electrode active material layer is a negative electrode active material layer, the second electrode active material layer is a positive electrode active material layer.
