Abstract
The main object of the present invention is to provide an all solid state battery in which compatibility between battery performance and safety is intended. The present invention attains the object by providing an all solid state battery comprising a cathode layer containing a cathode active material, an anode layer containing an anode active material, and a solid electrolyte layer formed between the cathode layer and the anode layer, containing a first sulfide solid electrolyte material, characterized in that a ratio of ion resistance of the whole all solid state battery to ion resistance of the solid electrolyte layer is 3.8 or less, and the ion resistance of the solid electrolyte layer is 7.6 Ω·cm2 or more and 16 Ω·cm2 or less.
