The present invention provides a graphite material comprises a graphite containing a plurality of pores, wherein the graphite and the plurality of pores to form a microstructure. When observing the cross section of the microstructure with a scanning electron microscope, the number of the pores shown in the cross-section is 6000 ㎛ ² per more than 250, and the average area of the pore shown in the cross-section is 5 ㎛ ² below, shown in the cross-section the average flat rate of pores (aspect ratio) is not more than 0.55. Graphite materials, the microstructure, the elastic body, a coil spring, EDM
