Resin composition and heat-dissipating member

Abstract

There is provided a resin composition containing a first filler that is at least one selected from the group consisting of octahedral diamond and hexoctahedral diamond, a second filler different from the first filler, and a matrix resin, wherein the volume-average particle diameter for primary particle diameter of the first filler is larger than the volume-average particle diameter for primary particle diameter of the second filler; the volume percentage of the whole of the fillers is higher than 80% by volume, and the volume percentage of the diamond is higher than 20% by volume; and the volume-average particle diameter for primary particle diameter of the first filler is 55 μm or larger.
