description PROBLEM TO BE SOLVED: To enhance the performance of a sodium secondary battery, restraining lowering and deteriorating the performance level of the sodium secondary battery, and to manufacture high-performance sodium secondary battery easily and safely. SOLUTION: A cylindrical partition plate 32 is arranged in a positive pole activator housing part B on the outer peripheral side of a cylindrical body 4'. A gap 33 is formed between the outer surface of the cylindrical body 4' and the inner surface of the partition plate 32, and the state with the gap 33 being filled with a positive electrode active material 3 is maintained. A guard tube 9' provided with a communicating hole 10 in the bottom end part thereof is arranged in the cylindrical body 4'; a gap 11 is formed between the guard tube 9' and the cylindrical body 4'. The state in which the gap 11 is filled with a negative electrode active material 2 is maintained; and accordingly, the liquid level of the positive electrode active material 3 and the liquid level of the negative electrode active material 2 do not change at charging/ discharging, the high-performance sodium secondary battery 31 can be obtained, without lowering and deteriorating the performance level.
