The present invention provides a magnesium secondary cell comprising a positive electrode, a negative electrode releasing magnesium ions, and a nonaqueous electrolyte. The nonaqueous electrolyte comprises a solvent and a magnesium sulfonamide salt represented by formula (I) below, Mg[X1—SO2—N—SO2—X2]2 (I) wherein X1 and X2 are identical or different and each represents CpF2p+1, or X1 and X2 are taken together to represent CqF2q, wherein p is 0, 1, 2, or 3, and q is 2, 3, or 4. The solvent is a mixed solvent comprising a sulfone-based solvent and an ether- or thioether-based solvent, or the solvent is a solvent comprising a sulfone moiety and an ether or thioether moiety.
