A composite material having a plurality of laminated polysilylenemethylene layers each having an inside region adjacent to a surface thereof in which nanoparticles of a metal of Au, Pt, Pd, Cu or Ag are dispersed. The composite material is produced by heating a layer of disilacyclobutane overlaid with a layer of nanoparticles of the above metal to polymerize the disilacyclobutane. The above procedure is repeated at least once more.
