Abstract
A solid-state battery having a low heat generation amount and low resistance, and a method for producing the same. The solid-state battery is a solid-state battery comprising: a cathode comprising a cathode layer that contains an oxide-based cathode active material, an anode comprising an anode layer that contains an anode active material, and a solid electrolyte layer being disposed between the cathode layer and the anode layer and containing a solid electrolyte, wherein at least any one of the cathode layer and the solid electrolyte layer contains a sulfide-based solid electrolyte, and wherein the sulfide-based solid electrolyte comprises a high oxygen concentration layer on a contact surface with the oxide-based cathode active material, the high oxygen concentration layer having a higher oxygen element concentration than other parts except the contact surface.
