PROBLEM TO BE SOLVED: To provide a sintered oil retaining bearing which is provided with a clearance, which is not in contact with a rotary shaft, about the inside diameter of an axial central part and a shaft support surface at each end, wastes less lubricating oil and has stabilized force for supporting the rotary shaft, by equalizing the amount of pores on the shaft support surface. SOLUTION: After a support material 10 is pressed into a tapered drawing part 21, the end face of the bearing material 10 is pressurized axially for compression by a contraction amount of 1-5% or less of the axial dimension of the bearing material.
