Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a sintered body of metal powder having a layer which has density almost equal to full density when sintered. SOLUTION: The method for manufacturing the sintered body of the metal powder includes the steps of: uniaxially compacting the metal powder; presintering the formed compacted body in the temperature range of at least 500°C; and subjecting the presintered compacted body to shot peening or rolling, wherein a densified surface layer with at least 0.1 mm depth region from the surface is formed by the shot peening or rolling and the densified surface layer has 90-100% density of the full density when sintered.
