Abstract
Disclosed is an all-solid-state battery that makes it possible for a larger rounding current flow into a short-circuit current shunt part than to each electric element when the short-circuit current shunt part and the electric elements short-circuit in nail penetration testing. The all-solid-state battery includes at least one short-circuit current shunt part and a plurality of electric elements, the short-circuit current shunt part and the electric elements being stacked, wherein the short-circuit current shunt part includes a first current collector layer, a second current collector layer, and an insulating layer provided between the first and second current collector layers, all of the layers being stacked, each of the electric elements includes a cathode current collector layer, a cathode material layer, a solid electrolyte layer, an anode material layer, and an anode current collector layer, all of the layers being stacked, the electric elements are electrically connected to each other in parallel, the first current collector layer is electrically connected with the cathode current collector layer, the second current collector layer is electrically connected with the anode cur…
