Abstract
An object of the present invention is to provide a technique capable of realizing good wear resistance with a simple structure. A sliding member and a sliding bearing each include a base layer and a coating layer formed on the base layer, the coating layer having a sliding surface with a counterpart member. The base layer is formed of a hard material that is harder than the coating layer, and the average concentration of a diffusion component of the hard material diffused from the base layer is 4 wt % or more in an evaluation range, in the coating layer, in which the distance from an interface with the base layer is 1 μm or more and 2 μm or less.
Claims6
