A ceramic member composed of a ceramic material which is coated with a solid lubricating film. The solid lubricating film is formed on the surface of the ceramic material by heating and evaporating in a vacuum atmosphere having a vacuum degree of not less than 10.sup.-4 Torr an organic material which has a vapor pressure of not more than 10.sup.-4 Torr at room temperature while implanting the ions of a gas element having an energy of not less than 1 keV on the surface of the organic material at the rate of not less than 1.times.10.sup.15 ions/cm.sup.2. A method of forming such a solid lubricating film on the surface of a ceramic material is also disclosed.
