Stage: PROBLEM TO BE SOLVED: To provide a lithium secondary battery in which a lithium metal and/or a lithium alloy is used as a negative electrode active material and in which capacity retention rate is enhanced, resistance is reduced, and a short circuit can be suppressed.SOLUTION: A lithium secondary battery includes a negative electrode current collector layer 111, a negative electrode active material layer 112, a protective layer 113, an electrolyte layer 120, a positive electrode active material layer 131, and a positive electrode current collector layer 132, in this order. The negative electrode active material layer 112 contains a lithium metal or a first lithium alloy, and the protective layer 113 contains a second lithium alloy different from the first lithium alloy.SELECTED DRAWING: Figure 1 (Grant)
