Summary:PURPOSE:To offer a nonaqueous electrolyte secondary battery having an excellent cycle characteristic by improving a negative electrode in this invention. CONSTITUTION:A cycle characteristic is improved with the expansion or collapse of a negative electrode 1, due to inserting and releasing lithium at the time of charging and discharging, restrained by using a compound oxide of lithium and transition metals, particularly iron or tungsten, as a negative electrode material of a nonaqueous electrolyte secondary battery having a positive electrode 4, negative electrode 1, and nonaqueous electrolyte battery.
