Abstract
Disclosed is a sliding member having a bearing alloy layer and a composite plating film provided on the bearing alloy layer. The composite plating film is made of a lead alloy containing 0.1 to 10 mass percent in total of copper and 0.3 to 25 volume percent in total of co-deposited inorganic particles. The outermost surface layer of the composite plating film, which has a thickness proportion of 10 to 40% to the entire thickness of the composite plating film, does not contain inorganic particles and copper. The lower layer of the composite plating film contains Cu and inorganic particles, such as Si N , dispersed therein.
