description An object of the present invention is to provide a negative electrode active material etc. which have a high capacity density and which can improve cycle characteristics of a sodium secondary battery using a molten salt electrolyte. The negative electrode active material for a sodium secondary battery using a molten salt electrolyte includes tricobalt tetroxide. In the negative electrode active material, the tricobalt tetroxide preferably has an average particle size d50 of 10 μm or less and a maximum particle size dmax of 30 μm or less.
