In a non-aqueous electrolyte secondary battery provided with a positive
electrode, a negative electrode using carbon material as negative
electrode active material, and a non-aqueous electrolyte solution, the
non-aqueous electrolyte solution contains at least a saturated cyclic
carbonic ester and a cyclic carbonic ester having C.dbd.C double bond
where an amount of the cyclic carbonic ester having C.dbd.C double bond
is in a range of 1.0.times.10.sup.-8 to 13.0.times.10.sup.-5 g per
negative electrode capacity of 1 mAh.
