摘要

A slide member (4) provided with an Al-based alloy layer (1) including Si and having a first contoured surface having first planar surfaces and first convexities consisting of Si particles protruding from the first planar surfaces; an intermediate layer (2) that coats the Al-based alloy layer; an overlay (3) that coats the intermediate layer; wherein 90% or more of the Si particles protruding from the first planar surfaces are configured to have a predetermined particle diameter of 2 µm or less, the Si particles having the predetermined particle diameter being distributed in the Al-based alloy layer with a distance between centers of gravity of the Si particles having the predetermined particle diameter averaging 6 µm or less, and wherein the overlay has a second contoured surface having second planar surfaces and second convexities conforming with the first planar surfaces and the first convexities of the first contoured surface.
