The DC resistance of polycrystalline fullerene C 60 and graphite in the temperature range 77–450 K were studied at pressures up to 50 GPa. The AC measurements were performed at room temperature. The temperature and pressure dependences of resistance for both materials are of a similar character. However, the resistance of both materials is different by many orders of magnitude. It is shown that both fullerene and graphite keep some features of their original microscopic structure even at high pressures.
