Stage: PROBLEM TO BE SOLVED: To provide a lithium metal secondary battery in which a capacity retention rate is enhanced and a resistance value is reduced.SOLUTION: A lithium metal secondary battery includes a negative electrode current collector layer 111, a metal layer 112, a negative electrode active material 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 113 contains a lithium metal and a metal particle 114 dispersed in the lithium metal, the metal particle 114 contains a metal element that is taken with lithium to form an alloy, and the area ratio of the metal particle 114 is 1x10-5% to 50% in observation of a cross section of the negative electrode active material layer 113 in a full charge state.SELECTED DRAWING: Figure 1 (Grant)
