1. A solid-state battery comprising:
a solid-state battery laminate that includes at least one 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 along a lamination direction, and defining:
an overlapping part in which the positive electrode layer and the negative electrode layer overlap each other in the lamination direction, and
a non-overlapping part in which the positive electrode layer and/or the negative electrode layer do not overlap each other in the lamination direction; and
the solid-state battery laminate has a recess on at least one main surface having a normal in the lamination direction, the recess overlapping the overlapping part and defining a step between the overlapping part and the non-overlapping part or in the non-overlapping part.
