The characteristics of graphite have been characterized as a function of porosity. In order to further reduce the characteristic variation and to characterize them with high accuracy, it is necessary to characterize them as a function of some detailed factors. Therefore, we focused on the open and closed pore of graphite and analyzed them based on two and three dimensional images to develop the prediction method for thermal conductivity of graphite. In the present study, it was reported analytical results of pore distribution and comparison result of predicted thermal conductivity to the experimental one.
