PROBLEM TO BE SOLVED: To provide a heat-transfer-emission material having a high heat conductivity and a heat-emission property, and excellent in the electric insulation characteristic. SOLUTION: The heat-transfer-emission material 10 of this embodiment comprises a plate-like heat emission ceramics 11 and a heat conductive sheet 12 mutually laminated. The heat emission ceramics 11 of the heat-transfer-emission material 10 of this embodiment has a high thermal emissivity to be able to suppress an increase in temperature of a heat generator 14. In addition, it provides excellent insulation and does not act as a reradiation body of electromagnetic wave noise generated from an electronic substrate and an electronic component such as an IC, a LSI, a semiconductor, or the like. In addition, the heat conductive sheet 12 is excellent in heat conductivity to be able to efficiently conduct the heat of the heat generator 14 to the heat emission ceramics 11. Further, the heat conductive sheet 12 has flexibility to stick to the surface of the heat generator 14 and the heat emission ceramics 11 even though their surface are concavoconvex, lowering thermal resistance, which can efficiently transmit the heat to the heat emission ceramics 11.
