Zusammenfassung:	To provide a slide member of which friction characteristic can be easily improved, and a method for manufacture of the same.SOLUTION: A slide member 10 in which a slide part 11 is made from a metallic material, and a surface layer part of the slide part 11 has a modified layer 12 which is formed by projection of a projection material which contains Cr as a composition and contains Cr. The slide member 10 is slid under environment of a lubrication oil which contains Mo as an additive, an active Cr, which is exposed to a surface by slide thereof, promotes decomposition reaction of the additive contained in the lubrication oil, and a coating, which contains molybdenum disulfide having low friction, is formed on the surface of the slide part 11.SELECTED DRAWING: Figure 1 【課題】容易に摩擦特性を向上させることができる摺動部材及びその製造方法を提供する。【解決手段】摺動部材１０は、摺動部１１が金属材料よりなり、摺動部１１の表層部に、組成としてＣｒを含む投射材を投射することにより形成されたＣｒを含む改質層１２を有している。摺動部材１０は、添加剤としてＭｏを含む潤滑油環境下で摺動するものであり、摺動により表面に露出した活性なＣｒが潤滑油に含まれる添加剤の分解反応を促進し、摺動部１１の表面に、低摩擦である二硫化モリブデンを含む被膜を形成させる。【選択図】図１
