A nonaqueous electrolyte secondary battery according to an embodiment includes a spirally wound electrode body in which a positive electrode and a negative electrode are spirally wound with a separator interposed therebetween. The negative electrode includes a negative electrode current collector, a first negative electrode mixture layer disposed on a first surface of the negative electrode current collector, and a second negative electrode mixture layer disposed on a second surface of the negative electrode current collector. The first surface and the second surface face outward and inward of the electrode body, respectively. At least the first negative electrode mixture layer includes a Si active material. The content of the Si active material in terms of Si in the second negative electrode mixture layer is lower than the content of the Si active material in terms of Si in the first negative electrode mixture layer.
