A nonaqueous electrolyte secondary battery comprising positive and negative electrodes capable of absorbing and desorbing lithium ions; a nonaqueous electrolytic solution; and a separator provided between the positive electrode and the negative electrode. The negative electrode comprises a negative electrode active material layer containing at least a styrene polymer as a binder in a content of 0.3 to 8.0 mass% based on the total mass of the negative electrode active material layer. The nonaqueous electrolytic solution contains at least a cyclic sulfonic acid ester including two sulfonyl groups in a content of 0.002 to 5.0 mass% based on the total mass of the nonaqueous electrolytic solution.
