Provided is a non-aqueous electrolyte secondary battery that is capable of improving low-temperature input/output characteristics. The non-aqueous electrolyte secondary battery has a battery element (10) including a positive electrode member (11), a negative electrode member (12), and a non-aqueous electrolyte solution. The negative electrode member (12) contains graphitizable carbon. With respect to 100 parts by weight of the non-aqueous electrolyte solution, fluoroethylenecarbonate is added at 0.5 parts by weight or more and 1.0 parts by weight or less, and lithium difluorobis(oxalato)phosphate is added at 0.5 parts by weight or more and 1.0 parts by weight or less, or fluoroethylenecarbonate and lithium difluorobis(oxalato)phosphate are added at 0.5 parts by weight or more and 2.0 parts by weight or less in total. |
