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. The composite material compressed by 10% has a reaction force of 0.1 kPa to 1000 kPa, and the composite material has a heat conductivity of 0.5 W/(m·K) or more. The 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 (ASTM) D5470-01.
