An all-solid-state battery capable of operating under a high voltage and excellent in ion conductivity is provided. A positive electrode, a solid electrolyte layer, and a negative electrode are provided. The solid electrolyte layer is composed of a first solid electrolyte that is stable at a voltage of 5.6 V, and a second solid electrolyte that has an ionic conductivity of 1 × 10 −6 S / cm or more. A second solid electrolyte layer comprising: The solid electrolyte layer is an all-solid battery in which the first solid electrolyte layer is disposed closer to the positive electrode than the second solid electrolyte layer.
