A sliding bearing includes a center portion and end portions on a bearing surface 1. Convexo-concave portions are respectively formed in the center portion and the end portions. The average height of the vertexes of convex portions 1A in the center portion is set smaller than the average height of the vertexes of convex portions 1B in the end portions. Average height L h of the convexo-concave portion 1A in the center portion and average height L H of the convexo-concave portions 1B in the end portions are set to the same height. The center portion may be formed flat. It is possible to attain a reduction in friction without sacrificing conformability and a load capacity. |
