Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lubricant composition having high performance.SOLUTION: Provided is a lubricant composition comprising: a lubricant; and silica particles in which the volume average particle diameter is 5 to 200 nm and dispersed into the lubricant in almost the state of the primary particles. Since the particle diameter of the dispersed silica particles is extremely small, and also, they are present almost in the state of the primary particles, the action of a roller by the silica particles to a degree not predicted from the conventional case can be expected. 【課題】高性能な滑剤組成物を提供すること。【解決手段】滑剤と、体積平均粒径が５ｎｍ以上２００ｎｍ以下であり概ね一次粒子の状態で前記滑剤中に分散されたシリカ粒子とを有する。分散するシリカ粒子の粒径が非常に小さく且つ一次粒子の状態で存在するため従来からは予測できない程度のシリカ粒子による「ころ」としての作用が期待できる。【選択図】なし
