PROBLEM TO BE SOLVED: To provide a laminated sliding member having characteristics excellent in both seizure resistance and fatigue resistance without including harmful Pb and even under a severe condition of high temperature and high surface pressure, and to provide a sliding bearing having the laminated sliding member on its surface layer and excellent in seizure resistance and fatigue resistance. SOLUTION: This laminated sliding member is formed by laminating as a surface layer an Sn group alloy B on a bearing alloy A consisting of Sn: less than 6-15%, Si: 0.1-4.5%, one kind or two kinds selected from Cu, Cr: 0.1-2% by wt.% respectively, and a balance substantially formed of Al. Sn group alloy B as the surface layer consists of In: 0.1-15%, Cu: 0.1-5% by wt.% respectively, a solid lubricant of 5-20 vol.% consisting of one kind or more than two kinds selected from MoS2, WS2, graphite, PTFE and hBN, and a balance substantially formed of Sn. The layer thickness of the Sn group alloy B is set to not less than 1/40 nor more than 1/10 of the thickness of the bearing alloy A. A sliding bearing uses the laminated sliding member on its sliding surface side.
