摘要： A task of the present invention is to provide a non-aqueous electrolyte secondary battery which exhibits small initial irreversible capacity and high initial efficiency as well as excellent high-temperature cycle characteristics without sacrificing the yield of the battery. The non-aqueous electrolytic solution of the present invention is a non-aqueous electrolytic solution for use in a non-aqueous electrolyte secondary battery which comprises a positive electrode capable of having occluded therein and releasing metal ions, a negative electrode capable of having occluded therein and releasing metal ions, and a non-aqueous electrolytic solution comprising a non-aqueous solvent and an electrolyte dissolved in the non-aqueous solvent, wherein the non-aqueous electrolytic solution contains a compound represented by the general formula (1) in an amount of 0.01 to 4.5% by mass, based on the mass of the non-aqueous electrolytic solution:

wherein, in the general formula (1), n represents an integer of 1 to 4, and R 1 to R 3 represent predetermined groups.
