Abstract
A method for producing an all solid state battery in which an anode foil, an anode layer, a solid electrolyte layer, and a cathode layer are layered in this order, and an area of the solid electrolyte layer and the anode layer is larger than an area of the cathode layer is disclosed. The method includes a first pressing step of roll-pressing a first layered body so an adhesive force between the anode foil and the anode layer becomes 30 N/cmor more, to form a second layered body; a layered body forming step of forming a third layered body comprising the anode foil, the anode layer, the solid electrolyte layer, and the cathode layer, using the second layered body; and a second pressing step of roll-pressing the third layered body with a linear pressure of 1.0 t/cm or more to form a forth layered body.
