It is an object of the present invention to provide a nonaqueous electrolyte secondary battery improved in output after storage in a charged state. An embodiment of the present invention provides a nonaqueous electrolyte secondary battery including an electrode assembly having a structure in which a positive plate and a negative plate are stacked with a separator therebetween. The positive plate contains tungsten and a phosphate compound. The negative plate contains a graphitic carbon material as a negative electrode active material and a noncrystalline carbon material stuck on the surface thereof. The negative plate contains tungsten or a tungsten compound on the surface of the noncrystalline carbon material.
