The present invention relates to a heat sink sheet including an adhesive containing a carbon nano complex and having good heat conductivity. The adhesive having good heat conductivity is coated on a graphite sheet to improve heat conductivity, and an existing adhesive process and adhesive coating process are combined into a single process to manufacture a heat sink sheet, thereby providing a heat sink sheet having improved heat conductivity so as to contribute to cost reduction and increased yield. La présente invention concerne une feuille de drain thermique comportant un adhésif bon thermoconducteur contenant un nano-complexe de carbone. Cet adhésif bon thermoconducteur est appliqué sur une feuille de graphite de façon à améliorer la thermoconductivité. Pour fabriquer cette feuille de drain thermique, on réunit en un seul procédé le procédé de fabrication de l'adhésif et le procédé d'application de l'adhésif. La feuille de drain thermique ainsi obtenue présente une meilleure thermoconductivité, et le procédé de production permet de réduire les coûts et d'augmenter le rendement.
