PROBLEM TO BE SOLVED: To provide an all-solid-state battery using a high voltage material as a positive electrode active material and reduced in the interface resistance between the positive electrode active material and a solid electrolyte material.SOLUTION: According to the present invention, an all-solid-state battery is provided to solve the problem. The all-solid-state battery includes: a positive electrode active material layer containing a positive electrode active material having an average actuation voltage of 4 V(vs. Li/Li) or more; a negative electrode active material layer containing a negative electrode active material; and a solid electrolyte layer formed between the positive electrode active material layer and the negative electrode active material layer. In the all-solid-state battery, a modifying material having a dielectric constant higher than that of a solid electrolyte material is arranged at an interface between the positive electrode active material and the solid electrolyte material. |
