The present invention is capable of providing a heat-conductive resin composition containing 70 to 20 parts by volume of (A) a polyester resin having a melt viscosity at 200°C and 10 kgf loading of 5 to 10,000 dPa·s, and 30 to 80 parts by volume of (B) a heat-conductive filler, wherein the heat-conductive resin is characterized in that the heat-conductive filler (B) contains zinc oxide and magnesium oxide and is a mixture of two or more types having different average particle sizes, the zinc oxide having a smaller average particle size than that of the magnesium oxide. The highly heat-conductive resin composition exhibits excellent performance as a filler and excellent heat and humidity resistance. |
