The present disclosure aims to provide a nonaqueous electrolyte secondary battery having excellent discharge load characteristics and excellent long-term cycle characteristics. A nonaqueous electrolyte secondary battery which is one example of an embodiment of the present disclosure includes a positive electrode, a negative electrode (), separators, and a nonaqueous electrolyte. The negative electrode () includes a negative electrode collector () and a negative electrode mixture layer () formed on the negative electrode collector (). The negative electrode mixture layer () includes a first mixture layer primarily composed of a carbon-coated graphite () and a second mixture layer () primarily composed of a graphite (), the first mixture layer () is disposed at a surface side of the negative electrode mixture layer (), and the second mixture layer () is disposed at a side of the negative electrode collector ().
