SOLID STATE LITHIUM SECONDARY BATTERY AND METHOD FOR PRODUCING THE SAME

The present invention provides a solid state lithium secondary battery in which the occurrence of a short circuit at the time of charging is suppressed. This object is attained by providing a solid state lithium secondary battery comprising an anode current collector (1), a solid electrolyte layer (2), a cathode active material layer (3), and a cathode current collector (4) in this order, wherein the solid electrolyte layer (2) is provided on the surface of the anode current collector (1), the solid electrolyte layer contains sulfide solid electrolyte particles, the thickness of the solid electrolyte layer is 50 µm or less, the outer periphery of the anode current collector (1) is formed inwardly of the outer periphery of the solid electrolyte layer (2) when viewed in a planar view, and the distance between the outer periphery of the solid electrolyte layer (2) and the outer periphery of the anode current collector (1) is 300 µm or more.
