  "textContent": "To provide a mixed carbon material used for an electrode of a nonaqueous secondary battery with excellent characteristics satisfying both rapid charge-discharge characteristics and high cycle characteristics. [0002] A negative electrode material for nonaqueous electrolyte secondary battery, comprising the following carbon material A and carbon material B: (Carbon material A) a multilayer-structure carbon material containing a graphitic particle and an amorphous carbon covering the surface of the graphitic particle, which is a carbon material where the interplanar spacing (d002) of 002 planes by the wide-angle X-ray diffraction method is 3.37 Å or less, Lc is 900 Å or more, the tap density is 0.8 g/cmor more, and the Raman R value that is a ratio of the peak intensity near 1,360 cmto the peak intensity near 1,580 cmin the argon ion laser Raman spectrum, is from 0.25 to 0.6, (Carbon material B) a eaxbon material where the interplanar spacing (d002) of 002 planes by the wide-angle X-ray diffraction method is 3.37 Å or less, Lc is 900 Å or more, the tap density is 0.8 g/cmor more, and the Raman R value that is a ratio of the peak intensity near 1,360 cmto the peak intensity near 1,580 cmin the argon ion laser Raman spectrum, is from 0.11 to 0.2.",
