Abstract
An electrode for an all-solid-state battery includes an active material, a first solid electrolyte, and a second solid electrolyte. A mean particle diameter of the active material is greater than or equal to 0.01 μm and less than or equal to 0.7 μm. A mean particle diameter of the first solid electrolyte is greater than or equal to 0.01 μm and less than or equal to 0.7 μm. A mean particle diameter of the second solid electrolyte is greater than or equal to 0.7 μm and less than or equal to 2.0 μm.
