Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a positive electrode active material having a reduced particle size, and obtain a lithium sulfur battery superior in capacity and lifetime characteristics. SOLUTION: This lithium sulfur battery contains the positive electrode active material composed of sulfur element (S8) with the particle size D (v, 50%) of 10μm or less, sulfur series compound, and a mixture of these, and the average surface roughness Ra value is 5μm or less.
