This invention provides (i) a heat-transfer sheet which comes into close contact with a heat generator and a radiator when caught there between and can be used repeatedly, (ii) a method of using the heat-transfer sheet, and (iii) a heat transfer system comprising the heat-transfer sheet. The heat-transfer sheet is made of expanded graphite and disposed between a heat generator and a radiator, and its bulk density is less than 1.0 Mg/m3. Because its bulk density is low, it is easily compressed between the heat generator and the radiator even under low pressure to be put into close contact with them. Thus, the thermal resistance between the heat generator and the heat sink is low and, hence, the heat generator is efficiently cooled down.
