A Bearing or sliding member comprising a bearing alloy layer (1), an intermediate layer (2) of Ni or a Ni alloy formed on the bearing alloy layer (1), and an overlay layer (4) of a Sn alloy containing Cu formed on the intermediate layer (2). There exist Sn-Cu compounds (3) in the overlay layer (4), which protrudently extend from the intermediate layer (2). The hard Sn-Cu compounds (3) contribute to the overlay layer (4) in improving fatigue resistance property. A soft Sn matrix being rich in an outer surface region of the overlay layer (4) is responsible for keeping good conformability to have excellent anti-seizure property.
