ALL-SOLID-STATE BATTERY AND PRODUCTION METHOD OF THE SAME

Disclosed is an all-solid-state battery including a positive electrode, a negative electrode, and a solid electrolyte layer interposed between the positive electrode and the negative electrode. At least one of the positive electrode and the negative electrode contains first solid electrolyte particles. The solid electrolyte layer contains second solid electrolyte particles having ion conductivity. An average particle diameter D of the first solid electrolyte particles, and an average particle diameter D of the second solid electrolyte particles satisfy D>D
