Abstract
A solid-state battery that includes a cathode layer which occludes and discharges an electrode reactant ion, an anode layer which occludes and discharges the electrode reactant ion and partially faces the cathode layer, and a solid electrolyte layer between the cathode layer and the anode layer and including a high ion conductivity portion in a first region in which the cathode layer and the anode layer face each other, and a low ion conductivity portion facing the cathode layer in a second region in which the cathode layer and the anode layer do not face each other.
