Abstract: A solid-state battery including a solid-state battery laminate having a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer, each of the positive electrode layer and the negative electrode layer having an electrode active material. A first active material contour portion in which the electrode active material in one of the positive electrode layer and the negative electrode layer extends to a first plan-view contour of the solid-state battery laminate, and a first non-active material contour portion in which the electrode active material in the other of the positive electrode layer and the negative electrode layer does not extend to the first plan-view contour of the solid-state battery laminate face each other in a lamination direction.
