Abstract
A composite material according to the present invention includes a solid portion including inorganic particles and a resin. The composite material has a porous structure including a plurality of voids surrounded by the solid portion. In the composite material, a value P1 determined by the following equation (1) is 6 or more. In the equation (1), a heat conductivity is a value measured for one test specimen in a symmetric configuration according to an American Society for Testing and Materials (ASTM) standard D5470-01. P1=(the heat conductivity [W/(m·K)] of the composite material/an amount[volume %] of the inorganic particles)×100 Equation (1).
