Abstract
Provided is a sliding member capable of realizing the wear resistance effect by Si particles.The sliding member includes an aluminum alloy layer containing 7.0% by mass or more and 13.0% by mass or less of Sn, 6.5% by mass or more and 12.0% by mass or less of Si, 0.5% by mass or more and 3.0% by mass or less of Cu, unavoidable impurities, and a balance Al. Si particles are dispersed in the aluminum alloy layer. A Vickers hardness of a matrix of the aluminum alloy layer is 40 HV or more and 60 HV or less. A load resistance value, which is a product of a volume concentration and average area of the Si particles and the Vickers hardness of the matrix, is 0.00001 N or more and 0.00029 N or less.
