SOLID-STATE BATTERY

A solid-state battery including a solid-state battery laminated body including a positive electrode layer, a negative electrode layer, and a solid electrolyte interposed between the positive electrode layer and the negative electrode layer; a positive electrode terminal on a first side surface of the solid-state battery laminated body; and a negative electrode terminal on a second side surface of the solid-state battery laminated body, the second side surface facing the first side surface. In such a solid-state battery, in at least one electrode layer of the positive electrode layer and the negative electrode layer, a terminal contact end portion containing an electrode active material is in direct contact with the respective positive or negative electrode terminal, and a thickness of a non-terminal contact end portion in the electrode layer is smaller than a thickness of a central portion of the electrode layer.
