An object of the present invention is to provide a highly practical electrolytic solution which has a high oxidative decomposition potential, enables the dissolution and precipitation of magnesium to stably repeatedly proceed, and is easy to prepare. The present invention relates to an electrolytic solution for a magnesium battery comprising: a compound represented by the general formula (I), a Lewis acid or a compound represented by the general formula (A), and a solvent; and to the compound represented by the general formula (I). In the formula (I), two X's each independently represent a halogeno group, and R1 represents an alkyl group having 1 to 6 carbon atoms; an alkoxy group having 1 to 6 carbon atoms; a phenoxy group; a -OMgX group (X is the same as X described above); an aryl group having 6 to 18 carbon atoms which has, as a substituent, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a vinyl group, a phenyl group, a phenoxy group, a halogeno group or a -B(OMgX)2 group (X is the same as X described above) or is unsubstituted; or a monocyclic or bicyclic heterocyclic group which has, as a substituent, an alkyl group having 1 to 6 carbon atoms, an alkoxy group having 1 to 6 carbon atoms, a vinyl group, a phenyl group, a phenoxy group, a halogeno group, or a -B(OMgX)2 group (X is the same as X described above) or is unsubstituted. In the general formula (A), four R6's each independently represent an alkyl group having 1 to 6 carbon atoms, a perfluoroalkyl group having 1 to 6 carbon atoms, a phenyl group, or a perfluorophenyl group.
