PURPOSE: A sintered oilless bearing and a method for manufacturing the same are provided to achieve a sintered oilless bearing suitable for a high speed rotation by providing sufficient strength and lubricant property to the sintered oilless bearing. CONSTITUTION: A sintered oilless bearing includes a mixture consisting of 38 to 42 weight percent of bronze-mixed powder(2), 36 to 40 weight percent of copper powder, and 20 to 24 weight percent of copper coated iron powder(100). The mixture is mixed with 0.5 to 1 weight percent of lubricant. Then, the mixture is sintered between 730 and 790°C. At this time, the mixture is preliminarily heated between 420 and 450°C. Then, the sintered mixture is immersed in an oil container so as to allow oil to penetrate into the sintered mixture.
