Abstract
There is provided a thermally conductive composite material obtained by dispersing a thermally conductive filler in a matrix. The thermally conductive filler is a mixture including boron nitride particles with an average particle size of 10 μm to 100 μm and aluminum nitride particles with an average particle size that is 1/100 to ½ of the average particle size of the boron nitride particles, a content of the boron nitride particles is 60 volume % to 90 volume % with respect to a total amount of the boron nitride particles and the aluminum nitride particles, a content of the thermally conductive filler is 80 volume % to 95 volume % with respect to a total amount of the composite material, and a porosity of the composite material is 10 volume % or less.
