To provide a sliding bearing appropriate for a use environment wherein the sliding bearing is slid at a low speed and receives face pressure varying from low contact pressure to high contact pressure and its manufacturing method.
The sliding bearing 16 is formed by sintering metal powders including copper and iron wherein a sintered alloy layer 30 with a plurality of pores 31 which communicates with each other has a surface regarded as a sliding surface 34 for sliding relative to a shaft 22. The sliding surface 34 is treated with a surface modification by carburizing, nitriding or sulphonitriding treatment method. A recessed part 35 with molybdenum disulfide dispersed and permeated is formed by colliding molybdenum disulfide after the surface modification treatment.
