PURPOSE: Provided is a grease composition having wearing resistance under severe temperature condition, particularly ultra high or ultra low temperature and containing a solid lubricant. CONSTITUTION: The grease composition contains 60 to 99 wt.% of grease and 0.1 to 40 wt.% of solid lubricant having a diameter of 1 to 50 micrometer, which is particularly a dichalcogenide solid lubricant and is produced by mixing at least a transition metal selected from the group consisting of tungsten(W), molybdenum(Mo), niobium(Nb), thallium(Ta), titanium(Ti), vanadium(V) and chromium(Cr) with at least a group 6A metal selected from the group consisting of sulfur(S), selenium(Se) and tellurium (Te) in a mole ratio of 1:2.2 to 1:3.0, and heating the mixture at 800 to 1000 deg. C for 2 hours or less.
