An object of the present invention to an organic material derived from plants as a raw material, an alkali metal such as potassium element is sufficiently demineralized high purity high-temperature cycle characteristics are excellent non-aqueous electrolyte secondary battery negative electrode carbonaceous material and a lithium ion secondary using the same for to provide a cell. The non-aqueous electrolyte secondary battery negative electrode carbonaceous material is 0.1 or less, an average particle diameter as the carbonaceous material obtained by carbonizing an organic material of plant origin, a hydrogen atom and the atomic ratio of carbon atoms (H / C) according to the elemental analysis for D
v50 the peak furnace metric with 2 to 50μm, X-ray is the average spacing in a 002 plane determined by diffractometry 0.365 nm to 0.400 nm, a potassium element content of 0.5% by mass or less, elemental calcium content of 0.02 mass% or less, and butanol with a calculated true density of less than 1.54g / ㎤ 1.44g / ㎤ above.
