Abstract
A thermally conductive sheet includes a resin that is liquid under normal temperature and pressure, a resin that is solid under normal temperature and pressure, and a particulate carbon material, and the thermal resistance of the thermally conductive sheet under a pressure of 0.05 MPa is at most 0.30° C/W. In the thermally conductive sheet, the resin that is solid under normal temperature and pressure is preferably a thermoplastic fluororesin that is solid under normal temperature and pressure, and the resin that is liquid under normal temperature and pressure is preferably a thermoplastic fluororesin that is liquid under normal temperature and pressure.
