ABSTRACT:
A silica glass member shows a glassy carbon coating wherein a surface of a silica glass substrate of the silica glass member shows a mean surface roughness (R.sub.a) in a range of 0.03 .mu.m to 2 .mu.m and it is coated with a glassy carbon coating. The member is manufactured by chemically roughening the substrate to a surface roughness in the above recited range; coating the surface of the silica glass substrate with an organic raw material containing carbon, curing and thereafter carbonizing the film of the organic raw material by forming a glassy carbon coating.
