<P>PROBLEM TO BE SOLVED: To provide a sintered bearing achieving smooth lubrication by supplying sufficient oil to a sliding part even at a low temperature or during high speed sliding. Ž<P>SOLUTION: Pores 20 opened on a bearing surface 8a (8b) are impregnated with sealing compound 21 and solidified and sealed, to suppress the movement of oil from the opened pores 20 on the bearing surface 8a (8b) to inside of a sintered body caused by temperature change and pressure rise. Thus, for example, even at a low temperature, oil can be retained in the sliding part, to ensure excellent lubrication performance. Since recesses are formed by the pores 20 on the bearing surface 8a (8b) impregnated with the sealing compound 21, the recesses 22 can be made to function as oil reservoirs. By supplying oil retained in the recesses 22 to the sliding part, lubrication performance for example, during high speed sliding easily causing shortage of oil can be enhanced.
