ALL SOLID STATE BATTERY

A main object of the present disclosure is to provide an all solid state battery of which calorific value can be reduced while preventing internal short circuit from increasing. The present disclosure achieves the object by providing an all solid state battery comprising an anode active material layer and an anode current collector; wherein the anode current collector includes a coating layer containing an oxide active material and a conductive material, on a surface of the anode active material layer side; a ratio of a thickness of the coating layer with respect to a thickness of the anode active material layer is less than 20%; and a proportion of the conductive material in the coating layer is more than 0 weight % and less than 1.0 weight %.
