Claim 0:
1. A solid-state battery comprising:
a battery body that includes a plurality of adjacent elements, a first element of the plurality of adjacent elements including a first positive electrode drawn out to a first surface of the battery body and not drawn out to a second surface of the battery body, a first negative electrode facing the first positive electrode and drawn out to the second surface of the battery body and not drawn out to the first surface of the battery body, and a first solid electrolyte layer between the first positive electrode and the second negative electrode, a second element of the plurality of adjacent elements including a second positive electrode drawn out to the second surface of the battery body and not drawn out to the first surface of the battery body, a second negative electrode facing the second positive electrode and drawn out to the first surface of the battery body and not drawn out to the second surface of the battery body, and a second solid electrolyte layer between the second positive electrode and the second negative electrode, wherein the first surface and the second surface of the battery body face each other and are orthogonal to a laminating direction of the first element and second element of the plurality of adjacent elements;
a first external electrode on the first surface and electrically connected to the first positive electrode;
a second external electrode on the second surface and electrically connected to the first negative electrode;
a third external electrode on the second surface and electrically connected to the second positive electrode; and
a fourth external electrode on the first surface and electrically connected to the second negative electrode,
wherein the first external electrode and the fourth external electrode or the second external electrode and the third external electrode are integral so as to connect the first element and the second element in series.
