摘要： The present invention provides a nonaqueous electrolyte solution which contains: a nonaqueous solvent containing acetonitrile and vinylene carbonate; and a compound represented by general formula (1) R 1 -A-R 2 (wherein A represents a divalent group that has a structure represented by one of formulae (1-2) to (1-5); and each of R 1 and R 2 independently represents an aryl group, an alkyl group which may be substituted by a halogen atom, while having from 1 to 4 carbon atoms, an alkyl group, a vinylidene group which may be substituted by a halogen atom, or an aryl group which may be substituted by a halogen atom; or alternatively, R 1 and R 2 may combine with each other and form, together with A, a ring structure that may have an unsaturated bond). With respect to this nonaqueous electrolyte solution, the total content of the vinylene carbonate and the compound represented by general formula (1) is not less than 0.1% by volume but less than 10% by volume relative to the total amount of the nonaqueous solvent; and the content of the vinylene carbonate is lower than the content of the compound represented by general formula (1).
