    摘要： Provided is a laminate that is configured to suppress a deterioration in the all-solid-state battery even if the end part of the anode layer is cracked. The laminate may be a laminate comprising an anode layer, a solid electrolyte layer and a cathode layer in this order, wherein an area in a planar direction of the cathode layer is smaller than an area in a planar direction of the anode layer; wherein an end part of the cathode layer comprises, on the solid electrolyte layer, a thin film part having a smaller thickness than a thickness of a central part of the cathode layer; and wherein the end part of the cathode layer comprises, on the thin film part, a space part formed by a level difference between the thin film part and the central part.
