A sliding bearing 1 is formed into a cylindrical shape by placing abutting surfaces 11A and 12A of a pair of half-bearings 11 and 12 so as to abut against each other. Two foreign substance discharging grooves 5 and 5′inclined with respect to an axial direction of the sliding bearing 1 are formed on a sliding surface 3 adjacent to an inner circumferential edge 4 of the abutting surfaces 11A and 12A. When a lubricant is supplied to the sliding surface 3, a foreign substance 6 mixed in the lubricant is trapped by foreign substance discharging grooves 5 and 5′and then discharged out of the sliding bearing 1 from ends 5A and 5B (5A′and 5B′) open to end faces 7 and 8. It is thereby possible to provide the sliding bearing 1 with good foreign substance discharge characteristics.
