PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery using a carbon material as a negative electrode active material, which has excellent cycle life and excellent output characteristics at a high rate. SOLUTION: In a non-aqueous electrolyte secondary battery including a positive electrode 1, a negative electrode 2 using a carbon material as a negative electrode active material, and a non-aqueous electrolyte, at least a saturated cyclic carbonate is contained in the non-aqueous electrolyte. and esters, with the inclusion of a cyclic carbonic ester having double bond of carbon, a cyclic carbonate having a double bond in the carbon, the negative electrode capacity 1mAh per 1.0 × 10 -8 ~13.0 × 10 - The content was within a range of 5 g.
