Provided is a negative electrode for a non-aqueous electrolyte secondary battery, the negative electrode being unlikely to cause changes in thickness even when subjected repeated charge/discharge over a long period of time. The negative electrode includes a core material, and a negative electrode material mixture layer adhering to the core material. The negative electrode material mixture layer includes a particulate carbon material. The particulate carbon material has a breaking strength of 100 MPa or more. The particulate carbon material has a surface roughness Ra of 0.2 to 0.8μm. The negative electrode material mixture layer has a packing density of 1.4 to 1.6 g/cm3. In a diffraction pattern of the negative electrode material mixture layer measured by wide-angle X-ray diffractometry, the ratio of I(101) to I(100) satisfies 1.0<I(101)/I(100)<3.0, and the ratio of I(110) to I(004) satisfies 0.25≰I(110)/I(004)≰0.45.
