[Problem] To provide a nonaqueous electrolyte secondary battery exhibiting superior stability characteristics and having charge/discharge characteristics exhibiting a high-rate discharge stroke, even when a lithium-nickel-cobalt manganate and a spinel-type lithium manganate are used as the positive electrode active material. [Solution] A mixture having a specific ratio of a tungsten- and zirconium-modified lithium-nickel-cobalt manganate and a spinel-type lithium manganate is used as the positive electrode active material. Furthermore, a nonaqueous electrolyte having a specific ratio of the content of dimethyl carbonate and the content of a cyclic carbonate is used.
