Abstract
A thermally conductive sheet including: an acrylic polymer; a high-soda alumina in an amount of 70 to 75% by volume; and a magnesium hydroxide having a particle size smaller than a particle size of the high-soda alumina in an amount of 2.7 to 5.3% by volume, the magnesium hydroxide is coated with a higher fatty acid. The thermally conductive sheet has a compressive force required in a deformation with a compressibility of 20% or less of 200 N or less, and has a thermal resistance of 0.45° C./W or less.
