Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce internal resistance on the side of a positive electrode and to reduce dispersion of battery performance, in a sodium sulfur battery composed by arranging a solid electrolyte tube capable of passing sodium ions and a collector electrode for carrying a positive electrode current on its outermost circumference. SOLUTION: This sodium sulfur battery is composed by arranging the solid electrolyte tube and the collector electrode for carrying a positive electrode current on its outermost circumference. A positive electrode-side structure disposed between the collector electrode and the solid electrolyte tube is formed with only a high-resistance layer having resistivity larger than that of sodium polysulfide.
