Abstract
A halved sliding bearing is provided, two of which are paired into a cylindrical shape. The halved sliding bearing includes a steel back metal, and a bearing alloy layer, which serves as a sliding surface, on the inside of the steel back metal. A coat layer of Bi or a Bi-based alloy is formed on the outside back surface of the steel back metal. Preferably, the coat layer consists of 1 to 30 mass % of one or more of Sn, Pb, In, Ag and Cu and the balance being Bi and inevitable impurities.
