PROBLEM TO BE SOLVED: To provide a heat transfer sheet whose adaptability is improved while good heat conductivity is kept and the performance of heat conductivity is elevated as a whole, by paying attention to an expansive graphite sheet for improving the sheet having characteristics whose heat conductivity is approximately the same to that of a graphite film, and moreover its adaptability is not largely inferior. SOLUTION: A low density material 3 with a structure composed of lowering density of expansive graphite is formed on a surface of a sheet body 2. The low density material 3 is formed, the surface of the sheet body being fuzzed. COPYRIGHT: (C)2007,JPO&INPIT
