Patent ID: 8579994

Claim:
A method for producing a solid-state cell that comprises an electrolyte-electrode laminate having a negative electrode, a positive electrode and a solid electrolyte layer disposed between the negative and positive electrodes, the method comprising: a structure preparing step for preparing a structure, wherein the structure is selected from the group consisting of a first structure in which a negative electrode material powder layer and a solid electrolyte material powder layer are stacked, a second structure in which a positive electrode material powder layer and a solid electrolyte material powder layer are stacked, and a third structure in which a negative electrode material powder layer, a solid electrolyte material powder layer, and a positive electrode material powder layer are stacked in this sequence; an insulating member disposing step for disposing a heat-resistant insulating member which is in contact with an outer periphery of the structure in the stacking direction of the structure and surrounds the outer periphery; and a heat-compressing step for heat-compressing the structure and heat-resistant insulating member, at least an inner periphery of the heat-resistant insulating member and a region which is inside the inner periphery, in the stacking direction of the structure, with a pressing surface which has an outer periphery that is lamer than the inner periphery of the heat-resistant insulating member and which has a flat surface.
