A glassy carbon-coated article contains a graphite substrate and a glassy carbon coating applied on the graphite substrate. The coating has a thickness of 15 to 200 microns. The glassy carbon is obtained by heating a raw material containing a thermal decomposition product of an organic polymer and a heat resistant inorganic substance. The difference of thermal expansion coefficient between the glassy carbon and the graphite substrate is not higher than 1.5.times.10.sup.-6 /.degree.C.
