A heat dissipation member having excellent thermal conductivity and dielectric breakdown characteristics is able to be achieved by using a thermally conductive resin composition according to the present invention. A thermally conductive resin composition which is characterized in that: the blending ratio of a spherical boron nitride fine powder having an average particle diameter of 0.05-1.0 μm, an average circularity of 0.80 or more and a purity of boron nitride of 96% by mass or more to a boron nitride coarse powder having an average particle diameter of 20-85 μm and a graphitization index of 1.5-4.0 is from 5:95 to 40:60 in terms of volume ratio; and the total content of the spherical boron nitride fine powder and the boron nitride coarse powder in the resin composition is 40-85% by volume. A heat dissipation sheet which uses this thermally conductive resin composition. A heat dissipation member for electronic components, which uses this thermally conductive resin composition. |
