1. A nonaqueous electrolyte solution, comprising a compound represented by the following general formula (1), a solute, and a nonaqueous organic solvent:

OG Complex Work Unit Chemistry
[in the general formula (1),
R1 and R2 each independently represents PO(Rf)2 or SO2Rf,
Rfs each independently represents a fluorine atom or a C1-4 linear or C3-4 branched perfluoroalkyl group,
R3 and R4 each independently represents a hydrogen atom, a lithium ion, a sodium ion, a potassium ion, or a C1-12 linear or C3-12 branched alkyl group, wherein an oxygen atom may be included between the carbon atoms of the carbon atom-carbon atom bond in the alkyl group, or
R3 and R4 form a ring structure together with the nitrogen atoms to which they are bound, wherein R3 and R4, together with each other, form an alkylene group; an oxygen atom may be included between the carbon atoms of the carbon atom-carbon atom bond in the alkylene group; a side chain thereof may have an alkyl group; and an arbitrary hydrogen atom in the alkyl group and alkylene group may be substituted by a fluorine atom,
provided that in case where R3 represents a lithium ion, a sodium ion or a potassium ion, a bond of the nitrogen atom and R3 in the general formula (1) represents an ion bond, and in case where R4 represents a lithium ion, a sodium ion or a potassium ion, a bond of the nitrogen atom and R4 in the general formula (1) represents an ion bond].
