The purpose of the present invention is to provide an electrochemical device which is provided with an electrolyte solution, which exhibits a high current density and excellent safety, and with which dissolution and deposition of magnesium are stably repeated. Furthermore, the present invention relates to an electrolyte solution for the electrochemical device, said electrolyte solution including (1) a supporting electrolyte comprising a magnesium salt, and (2) at least one compound represented by general formula (I) (in general formula (I): n represents an integer in the range 0-6; the n R1s and the n R2s each independently represent hydrogen, a C1-6 alkyl group, or a C1-6 halogenoalkyl group; and A1 and A2 each independently represent -C(=O)-R3, -O-R5, -N(R4)-R3, -S-R3, -C(=O)-OR3, -O-C(=O)-R3, -C(=O)-N(R4)-R3, -N(R4)-C(=O)-R3, -SO2-R3, -N(R4)-SO2-R3, -O-B(OR5), -O-P(=O)(OR5)2, -CN, a monocyclic heterocyclic group, a cyclic acetal-derived group, a cyclic carbonate ester-derived group, or a cyclic carboxylic acid ester-derived group).
