A graphite material and a carbon material for a battery electrode suitable as an electrode material for a non-aqueous electrolyte secondary battery, and charge / discharge cycle characteristics, large current load characteristics, and discharge capacity are maintained at a high level, and an additional reverse capacity is provided. Providing excellent secondary batteries that are extremely small. In the peak intensity of O 1s obtained by HAX-PES measurement using 7940 eV hard X-rays, the oxygen amount a (mass%) between the surface of the particle and the depth direction up to 40 nm is 0. A graphite material satisfying 010 ≦ a ≦ 0.04, a graphite material having a coating, a graphite material in which a part of carbon fiber is bonded to the surface, and d 002 is 0.3370 nm with respect to the graphite material. A graphite material formed by blending the following spherical natural graphite or artificial graphite. [Selection figure] None |
