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.
