NOVELTY - A carbonaceous-material is obtained by carbonizing a plant-derived organic substance. The atomic ratio of hydrogen atoms with respect to carbon atoms contained in the carbonaceous-material is 0.1 or less. The carbonaceous-material has average particle diameter of 2-50 mu m. The amount of potassium and calcium elements contained in the carbonaceous-material is 0.5 %mass or less and 0.02 %mass or less, respectively. The average interplanar distance of plane (002) in the carbonaceous-material is 0.365-0.4 nm, when measured using X-ray powder diffractometry.    USE - Carbonaceous material is used for negative electrode used for non-aqueous electrolyte secondary battery used for vehicle (all claimed) e.g. electric vehicle, and portable electronic device e.g. mobile telephone and notebook personal computer.    ADVANTAGE - The carbonaceous material provides the non-aqueous electrolyte secondary battery with excellent cyclic characteristics, and is manufactured efficiently with high yield.    DETAILED DESCRIPTION - A carbonaceous-material is obtained by carbonizing a plant-derived organic substance. The atomic ratio of hydrogen atoms with respect to carbon atoms contained in the carbonaceous-material is 0.1 or less. The carbonaceous-material has average particle diameter of 2-50 mu m, and density of 1.44-1.54 g/cm3, when measured using butanol by pycnometer method. The amount of potassium and calcium elements contained in the carbonaceous-material is 0.5 %mass or less and 0.02 %mass or less, respectively. The average interplanar distance of plane (002) in the carbonaceous-material is 0.365-0.4 nm, when measured using X-ray powder diffractometry.
