The present application provides a magnesium-sulfur secondary battery 20, which includes a positive electrode 23, an electrolyte layer 24A, and a negative electrode composed of a layered structure in which a positive electrode active material layer 23A containing sulfur or a sulfur compound and a carbon material layer 23B are stacked. 25. In this magnesium-sulfur secondary battery 20, a positive electrode active material layer 23A, a carbon material layer 23B, and an electrolyte layer 24A are sequentially arranged, and the positive electrode active material layer 23A and the carbon material layer 23B are in close contact. |
