Abstract
A composite member includes a structural member having a surface in a mirror-finished condition and a film layer of an amorphous material provided on the surface. The amorphous material is preferably at least one selected from amorphous SiC, amorphous SiN, amorphous SiGe and amorphous GeN. In producing the composite member, a surface of a structural member is polished into a mirror-finished condition which is a finish condition by the usual mirror-finishing. The film layer of the amorphous material is then provided on the surface in the mirror-finished condition by plasma CVD process.
