Abstract: A molten salt battery is provided which includes a positive electrode including a positive-electrode active material represented by the general formula: An(1−x)M1nxFe1−yM2yP2O7 (wherein n is 1 or 2, 0≦x≦0.5, 0≦y≦0.5, A is an alkali metal element, M1 is an element other than the element A, M2 is an element other than Fe), a negative electrode including a negative-electrode active material, a separator interposed between the positive electrode and the negative electrode, and a molten salt electrolyte. The molten salt electrolyte contains 90% by mass or more of an ionic liquid containing a salt of the element A.
