Abstract
A composite material used for a resin mold for forming hardened resin by hardening fluid resin is provided. The composite material comprises a first material having excellent wear resistance against the fluid resin and a second material having excellent unwettability against the fluid resin. The resin mold comprises a substrate of the first material, a large number of pores each provided to form an opening on a surface of the substrate opposite to the fluid resin and a film of the second material formed along the inner wall surface of each pore at least around the opening. Each of the large number of pores is a communicating hole connecting the surface opposite to the fluid resin and the remaining surface with each other. Therefore, releasability between a mold surface and the hardened resin and wear resistance of the composite material against the fluid resin can be improved.
