The sliding bearing (bearing sleeve (8)) includes an oxide powder compact in which particles (11) are bonded to each other by an oxide coating (12) formed on the surface of the particles (11) of the metal powder. The oxidized powder green compact is provided with bearing surfaces (A, B) which slide with a target material (shaft member (2)) to be supported via a lubricating film. The bearing surfaces (A, B) are provided with a plurality of openings (13a) whose communication with the internal pores (13b) is interrupted by the oxide coating (12). |
