Abstract
A main object of the present disclosure is to provide an all solid state battery with high coulomb efficiency even when the thickness of an anode active material layer is varied due to charge and discharge. The above object is achieved by providing an all solid state battery comprising: a power generation element including a cathode, a solid electrolyte layer, and an anode, in this order, and an exterior body storing the power generation element, and the anode includes at least an anode current collector, and the anode current collector includes a current collection part, and an elastic part placed on other side of the solid electrolyte layer, with respect to the current collection part.
