There are provided a novel carbon material having a characteristic property of a high volume electrical resistance, which is different from conventional carbon black. A carbon material of the present invention is insoluble in organic solvents, and has a peak height ratio H(B)/H(A) and a peak strength ratio I(D)/I(G) which are fall within the region defined by four points: (X, Y)=(0.86, 0.71), (0.65, 0.86), (0.28, 0.59) and (0.23, 0.63) in the coordinate system shown in FIG. 1 where the peak height ratio H(B)/H(A) is plotted as the X-axis and the peak strength ratio I(D)/I(G) as the Y-axis, wherein H(A) represents a height of the strongest peak at the diffraction angle 2 theta of 12-16° and H(B) represents a height of the peak at 2 theta=22° in the X-ray diffractometry using CuKalpha-rays, and I(G) represents a peak strength in the band of G1590±20 cm<SUP>-1 </SUP>and I(D) represents a peak strength in the band D1340±40 cm<SUP>-1 </SUP>in the Raman spectrometry at the excitation wavelength of 5145 Å. |
