Abstract

Disclosed is a sliding member having a predetermined shape and including: a sintered body obtained by sintering a composite body including: preliminary carbonized carbonaceous fiber; inorganic powder or inorganic fiber; and self-sintering carbonaceous powder with the preliminarily carbonized carbonaceous fiber and the inorganic powder or the inorganic fiber buried therein. The sliding member has a high and stable friction coefficient (.mu.), high strength, excellent abrasion resistance, and is manufacturable at a low cost. Further, the friction coefficient (.mu.) and the other properties of the sliding member can be controlled depending on an application of a sliding member by selecting an optimum inorganic powder or inorganic fiber. Particularly, when boron compound powder is selected as the inorganic powder, the friction coefficient (.mu.) of the sliding member can be suppressed to 0.15 or less, and the load at seizure thereof can be improved to 100 kgf/cm.sup.2 or more.
