Abstract:
1. A graphite composite material, obtained by mixing graphite material 1 comprising graphite particles each formed of an optical anisotropic structure, an optical isotropic structure and voids, and satisfying the following conditions (1) and (2): (1) when ten square regions with a side of 100 μm are randomly selected from a cross-section of a molding made of the graphite material (2) when 100 particles are randomly selected in cross-sections of the 100 particles, a maximum value of a length of a long-side portion of optical anisotropic structure domains is defined as L and graphite material 2 having a rhombohedron structure, which is different from graphite material 1 and has an average interplanar spacing d 002 of plane (002) of 0.3354 nm to 0.3370 nm measured by the powder X-ray diffraction method and a thickness Lc of a crystal in a C-axis direction of 100 nm or more.
