  "textContent": "A main object of the present disclosure is to provide an all solid state battery wherein the occurrence of a minute short circuit, in an anode active material layer located in a non-opposing region, is suppressed. The present disclosure achieves the object by providing an all solid state battery comprising a cathode, an anode, and a solid electrolyte layer, and the anode active material layer includes an anode active material, and a sulfide solid electrolyte, the anode current collector is a current collector that react with the sulfide solid electrolyte at an open circuit potential of the anode active material, the all solid state battery includes an opposing region, and a non-opposing region, the anode current collector includes a coating layer including lithium titanate, on a surface of the anode active material layer side, in plan view, the coating layer includes one or two or more of an existence portion and non-existence portion respectively, in the region specified by an outer edge of the anode current collector, and in plan view, the coating layer includes the existence portion in at least a part of the opposing region, and includes the non-existence portion in at least a part of the non-opposing region.",
