Summary:PROBLEM TO BE SOLVED: To provide an oil-impregnated metal powder sintered bearing capable of certainly holding an oil film formed on a sliding surface, decreasing oil consumption, and suppressing the unevenness in the rotation, and provide a method and device for manufacturing the bearing capable of making the setting so that an oil leak is generated in an appropriate region and preventing its rotary shaft from causing uneven rotation and seizure. SOLUTION: The oil-impregnated metal powder sintered bearing 1 is structured so that a bearing hole 4 to admit insertion of the rotary shaft 2 is formed in the bearing body 3 made of a sintered porous metal having voids internally, wherein one region on the end face 6 in the axial direction of the rotary shaft 2 is formed so that the voids opened at the end face 6 are crushed.
