Abstract
A heat-dissipating sheet having a density of 1.9 g/cmor more and an in-plane thermal conductivity of 570 W/mK or more, which comprises carbon black uniformly dispersed among fine graphite particles, a mass ratio of fine graphite particles to carbon black being 75/25 to 95/5, is obtained by repeating plural times a cycle of applying a dispersion of fine graphite particles, carbon black and an organic binder in an organic solvent to a surface of a support plate, and then drying it, to form a resin-containing composite sheet; burning the resin-containing composite sheet to remove the organic binder; and pressing the resultant composite sheet of fine graphite particles and carbon black for densification.
