description	본 발명은, 비정질 탄소질물 또는 흑연질물을 갖는 흑연을 포함하고, 수은 압입법으로 측정한 세공 분포가 2 개 이상의 피크를 갖고, 세공경이 최소인 피크와 다음의 피크 사이의 극소값 이하의 적산 세공 용적을 y (mL/g), 흑연의 비정질 탄소질물 또는 흑연질물의 코트율을 x (％) 로 했을 때에, y ≤ -0.0084x ＋ 0.13 을 만족하는 탄소재 (A) 와, 펠릿 밀도가 1.80 g/㎤ 이상인 탄소재 (B) 를 포함하는, 탄소재 조성물. The present invention provides a carbon material composition containing a carbon material (A) and a carbon material (B), in which the carbon material (A) contains graphite containing an amorphous carbonaceous material or a graphite material, has two or more peaks in a pore size distribution measured by a mercury porosimetry, and satisfies y ≤ -0.0084x + 0.13 wherein a cumulative pore volume in a range where a pore diameter is equal to or smaller than a pore diameter at a local minimum value between a peak of a smallest pore diameter and a peak of a second smallest pore diameter in the pore size distribution is defined as y (mL/g) and a coating rate of the amorphous carbonaceous material or the graphite material in the graphite is defined as x (%), and the carbon material (B) has a pellet density of 1.80 g/cm3 or more.
