Zusammenfassung:	PURPOSE:To obtain a solid lubricant having abrasion resistance, heat-resistance and low friction by coating molybdenum disulfide or tungsten disulfide with glassy carbon. CONSTITUTION:(A) Particle or block of molybdenum disulfide or tungsten disulfide is mixed with (B) a thermosetting resin most preferably composed of phenolic resin, furan resin, etc., and the mixture is calcined at about 600-2000 deg.C e.g. in nitrogen atmosphere to obtain the objective solid lubricant containing the component A as a core and a glassy carbon layer firmly bonded to the outer circumference of the core. Since glassy carbon has high wettability, the present lubricant enables the compounding of molybdenum disulfide or tungsten disulfide to synthetic resin, metal, ceramics, etc., at a high compounding ratio without lowering the mechanical strength of the base matrix.
