Abstract
An all solid state battery includes a cathode active material layer disposed in contact with a predetermined area of a cathode current collector, a solid electrolyte layer disposed on the cathode active material layer, and including a central part disposed on the cathode active material layer based on a stack direction of the all solid state battery, and a peripheral part extending from the central part and contacting the cathode current collector while surrounding side surfaces of the cathode active material layer, an anode layer disposed on the solid electrolyte layer and having an area greater than an area of the cathode active material layer but less than an area of the solid electrolyte layer, and a spacer disposed on the solid electrolyte layer and in contact with side surfaces of the anode layer.
