1. A solid-state battery comprising:
a laminate including a positive electrode plate and a negative electrode plate that are alternately laminated; and
a solid electrolyte layer formed on a lamination surface of the positive electrode plate and a lamination surface of the negative electrode plate,
the lamination surface of one electrode plate of the positive electrode plate and the negative electrode plate is larger in area than the lamination surface of the other electrode plate of the positive electrode plate and the negative electrode plate
an outer edge of the one electrode plate is positioned outside an outer edge of the other electrode plate,
the solid electrolyte layer is formed on at least a part of an end face of the one electrode plate,
the end face of the one electrode plate has a concave portion that is formed at a position corresponding to an electrode tab extending from the other electrode plate, and
the solid electrolyte layer formed on the other electrode plate extends on the concave portion.
