Abstract: Provided is a sliding bearing that can keep the price low while maintaining a bearing property over a long period. The sliding bearing is a sliding bearing 1 having a bearing periphery portion 2 formed of a metal base material, and a resin layer 3 formed on a surface to be a sliding surface of the bearing periphery portion, wherein the metal base material is an unsintered green compact formed by compacting a raw material powder containing a metal powder capable of forming an oxide film as a major raw material, and the oxide film has been formed between particles of the metal powder by means of steam treatment or the like, and the unsintered green compact has a radial crushing strength of more than 100 MPa.
