A solid-state battery that includes a solid-state battery laminate having at least one battery constituent unit in a lamination direction, the battery constituent unit including a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer; a positive electrode terminal on a surface of the solid-state battery laminate; and a negative electrode terminal on the surface of the solid-state battery laminate. In addition, the negative electrode layer includes a negative electrode active material configured to be charged and discharged at a potential of −2 V or less with respect to a standard electrode potential, and the negative electrode terminal includes a terminal material that does not react with lithium ions at a potential of −3 V to −2 V with respect to the standard electrode potential.
