METHOD OF MANUFACTURING ALL-SOLID-STATE BATTERY

To improve durability of an all-solid-state battery, a method of manufacturing an all-solid-state battery includes: obtaining a stack having an anode active material layer, a cathode active material layer, a first solid electrolyte layer, and a second solid electrolyte layer, the first solid electrolyte layer and the second solid electrolyte layer being disposed between the anode active material layer and the cathode active material layer, the second solid electrolyte layer containing a sublimational filler; densifying the stack; and subliming the sublimational filler from the second solid electrolyte layer.
