A heat-dissipating film comprising a heat-conductive layer comprising fine graphene particles and carbon nanotube uniformly dispersed, a mass ratio of the carbon nanotube to the total of the fine graphene particles and the carbon nanotube being 0.05-0.2; the fine graphene particles being substantially aligned with the heat-conductive layer; and the heat-conductive layer having a density of 1.9 g/cm 3 or more and thermal conductivity of 600 W/mK or more. |
