A composite bearing memberincludes: a bearing sliding materialwhose surface contacts a rotating portion; a bearing base materialmade of a material different from a material constituting the bearing sliding material; and a joining layerjoining the bearing sliding materialand the bearing base material. Further, the bearing sliding materialhas a sliding layersliding the rotating portion on a surface. Furthermore, the bearing sliding materialhas, between the sliding layerand the joining layer, a composition graded layerwhich dispersedly contains the same metal material as a metal material constituting the joining layerand in which a content of the metal material is increased toward the joining layer
