PROBLEM TO BE SOLVED: To provide a secondary battery having a high security, a low price, a high electric capacity density and a high charging voltage. SOLUTION: The battery comprises a negative electrode active material made of magnesium metal; a positive electrode active material made of a transition metal compound to which magnesium ions can be intercalated; an electrolyte of which the electrolyte solution contains a compound including an atomic group in which an aromatic atomic group and one halogen atom are bonded to a magnesium atom and a solvent composed of an ether-based compound solution. It is possible to set a discharge voltage to 2.3 V or higher. It is possible for the battery to be produced and used as a solid secondary battery by making the electrolyte be a polymer gel electrolyte containing a C<SB>6</SB>H<SB>5</SB>MgX (X=Cl, Br) and a polyethylene oxide (PEO).
