PROBLEM TO BE SOLVED: To provide: a nonaqueous electrolytic solution for a lithium secondary battery, which hardly causes corrosion of a collector when actuated under a condition of 4 V or more, even in a case where an imide-based alkali metal salt such as an imide lithium salt is used as an electrolyte, and with which stable drive of a battery can be expected; and a lithium secondary battery including the nonaqueous electrolytic solution.SOLUTION: A nonaqueous electrolytic solution for a lithium secondary battery of the present invention is a nonaqueous electrolytic solution for a lithium secondary battery that includes a positive electrode, a negative electrode and a nonaqueous electrolytic solution. The nonaqueous electrolytic solution includes: an imide-based alkali metal salt represented by general formula (1): MN(RSO)(RSO) (in the formula (1), M represents an alkali metal ion, and Rand Rindependently represent a fluorine atom or a 1-6C fluoroalkyl group), as an electrolyte; a solvent including a chain carbonate; and a compound including a sulfonic acid ester and/or a sulfone compound, as an additive. |
