Abstract
It is suppressed that an active material particle enters into or penetrates through a solid electrolyte layer when an active material layer and the solid electrolyte layer are pressed and that short circuits between a cathode and an anode occur. A method for producing an all solid-state battery includes: a first step of stacking an active material layer over at least one surface of a solid electrolyte layer to constitute a stack; and a second step of pressing the stack to constitute a compact, wherein in the first step, the active material layer contains a secondary particle of an active material, and in the second step, the secondary particle is crushed to primary particles by said pressing, the secondary particle being present in an interfacial portion between the active material layer and the solid electrolyte layer.
