Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonaqueous electrolytic solution secondary battery and a nonaqueous electrolytic solution to use this wherein decomposition of the electrolytic solution is less, charge-discharge efficiency is high, and storage characteristics and cycle characteristics in high-temperatures are superior. SOLUTION: In the nonaqueous electrolytic solution secondary battery containing a negative electrode and a positive electrode capable of occluding/ discharging lithium and an electrolytic solution in which a lithium salt is dissolved in the nonaqueous solvent, nitrile compound(s) having carbon-carbon unsaturated bond(s) is made to be contained in the electrolytic solution.
