The present invention provides a sliding member provided with an overlay capable of realizing good fatigue resistance while preventing peeling between layers. The present invention is a sliding member provided with an overlay formed by a Bi and Sb alloy plating film, wherein the overlay comprises Bi, Sb, and unavoidable impurities, and the concentration of Sb in the surface of the overlay is 0.92% by mass to 13% by mass. La présente invention concerne un élément coulissant pourvu d'un overlay capable de présenter une bonne résistance à la fatigue tout en empêchant le pelage entre les couches. La présente invention est un élément coulissant pourvu d'un overlay formé par un film de placage d'alliage de Bi et de Sb, l'overlay comprenant Bi, Sb et des impuretés inévitables, et la concentration de Sb dans la surface de l'overlay allant de 0,92 % en masse à 13 % en masse. 本発明は、層間の剥離を防止しつつ良好な耐疲労性を実現可能なオーバーレイを備えた摺動部材を提供する。 本発明は、ＢｉとＳｂの合金めっき被膜によって形成されたオーバーレイを備えた摺動部材であって、前記オーバーレイはＢｉとＳｂと不可避不純物とからなり、前記オーバーレイの表面におけるＳｂの濃度が０．９２質量％以上かつ１３質量％以下である。
