Abstract
There is provided a technique which can realize both of conformability and fatigue resistance.A sliding member and a slide bearing include a base layer and a coating layer provided on the base layer and having a sliding surface on which a counter material slides, and are characterized in that the coating layer is formed of a soft material which is softer than that for the base layer; and that, in the sliding surface, crystal grains of the soft material having an average grain diameter of 0.1 μm or more and 1 μm or less are aggregated into lumps, thereby forming aggregates having an average diameter of 3 μm or more and 30 μm or less.
