1. A solid-state battery comprising:
a multilayer body comprising a stack of a plurality of electrode layers including positive electrode layers and negative electrode layers and solid electrolyte layers each disposed between the electrode layers,
the multilayer body having a columnar shape;
the solid-state battery comprising:
a positive electrode terminal and a negative electrode terminal disposed at both end portions of the multilayer body;
a positive electrode tab electrically connected to the positive electrode layer and the positive electrode terminal;
a negative electrode tab electrically connected to the negative electrode layer and the negative electrode terminal,
wherein each of a plurality of the positive electrodes connects with the positive electrode tab at an outer peripheral surface of the positive electrode layer,
wherein each of a plurality of the negative electrodes connects with the negative electrode tab at an outer peripheral surface of the negative electrode layer; and
wherein the positive electrode tab and the negative electrode tab are spirally wound on an outer peripheral surface of the multilayer body.
