PROBLEM TO BE SOLVED: To provide a lubricant composition obtained by adding a powdery fluororesin as thickening agent in an appropriate proportion to a fluorine-based oil, excellent in antirust tendency and also good in antirust tendency after subjected to thermal history. SOLUTION: The lubricant composition comprises the fluorine-based oil, the powdery fluororesin as thickening agent and an aromatic sulfonic acid or saturated aliphatic dicarboxylic acid calcium salt or sodium salt as antirust additive. in this lubricant composition, the thickening agent and the additive account for 10-40 wt% and 0.3-10 wt% of the whole composition, respectively, the balance being the fluorine-based oil, wherein as the fluorine-based oil, a perfluoropolyether oil is normally used.
