Zusammenfassung:	A nonaqueous electrolytic solution secondary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent. The nonaqueous solvent contains 80% by mass or more of a cyclic carbonate which does not have a carbon-carbon multiple bond and which does not contain a halogen and contains a cyclic sulfone compound having any one of structures represented by the following formulae (1) to (4): wherein each of R1 and R2 represents CmH2m where 1 m 4. Also, each of R3 to R10 independently represents CnH2n+1 where 1 n 4.
