Claim 10:
11. An all-solid-state battery, comprising
a positive electrode, a negative electrode, and a solid electrolyte layer interposed between the positive electrode and the negative electrode,
wherein at least one of the positive electrode and the negative electrode contains first solid electrolyte particles,
wherein the solid electrolyte layer contains second solid electrolyte particles having ion conductivity,
wherein an average particle diameter D1 of the first solid electrolyte particles, and an average particle diameter D2 of the second solid electrolyte particles satisfy D2>D1,
wherein the average particle diameter D2 of the second solid electrolyte particles is 3 μm or more,
wherein the second solid electrolyte particles include a first group of particles each having a particle diameter of 1 μm or more, and a second group of particles each having a diameter of less than 1 μm,
wherein an average particle diameter D21 of the first group of particles of the second solid electrolyte particles, an average particle diameter D22 of the second group of particles of the second solid electrolyte particles, and the average particle diameter D1 of the first solid electrolyte particles satisfy D21>D1>D22, and
wherein the average particle diameter D22 of the second group of particles of the second solid electrolyte particles is 1 nm or more and less than 100 nm.
