PROBLEM TO BE SOLVED: To certainly and stably retain a porosity of 1.0% or less without raising a density of a bearing material. SOLUTION: In the method for manufacturing the sintered slide bearing, pores of a porous sintered body is impregnated/cured with a thermoset resin to perform sealing treatment and the sealing treatment by the resin are performed two times or more at the final step of the manufacturing of the bearing of the porous sintered body. Specifically, the method comprises a sintering step for sintering a pressure-molded powder body to manufacture the porous sintered body; a re-compression step for re-compressing the sintered body; and a sealing treatment step in which sealing operations in which pores of the re-compressed sintered body are impregnated/cured with a resin are performed two times or more.
