摘要： The present invention is for providing an oil-impregnant sintered bearing, which can reliably preserve an oil film on a sliding face, and a method for manufacturing the oil-impregnant sintered bearing. An oil-impregnant sintered bearing is made by providing an internal diameter, which a rotating axis member is inserted through, in a bearing main body, formed by a porous sintered alloy having internal pores therein, and providing a sliding face in one region of the inner peripheral face of the internal diameter, the sliding face being obtained by closing the pores which have been opened in the inner peripheral face. The density in a section preserving oil pressure, which extends from the sliding face of the bearing main body toward the outer side of the diameter, is made higher than the density in other sections of the bearing main body.
