    • A task is to provide a non-aqueous electrolytic solution exhibiting excellent cycle capacity maintaining ratio and excellent low-temperature resistance characteristics and a non-aqueous electrolyte secondary battery using the same. An object of the present invention is to provide a non-aqueous electrolytic solution which improves the cycle capacity maintaining ratio and low-temperature resistance characteristics, and a non-aqueous electrolyte secondary battery using the non-aqueous electrolytic solution. The present invention is a non-aqueous electrolytic solution comprising an electrolyte and a non-aqueous solvent dissolving therein the electrolyte, wherein the non-aqueous electrolytic solution contains a compound represented by formula (1) (wherein X represents an organic group containing a heteroatom, Y represents a sulfur atom, a phosphorus atom, or a carbon atom, n represents an integer of 1 or 2, m represents an integer of 2 to 4, 1 represents an integer of 1 or 2, and Z represents an organic group having 4 to 12 carbon atoms and optionally having a heteroatom), and a non-aqueous electrolyte secondary battery comprising the non-aqueous electrolytic solution.
