Abstract

To provide metallic powder for molding that has an excellent molding property and can produce a sintered body with high sintering density and an excellent surface property by sintering the obtained molding body and its manufacturing method.SOLUTION: Metallic powder for molding characterized in that it has metallic particles, where when D50 is the particle diameter with a 50% cumulative frequency in the volume-based particle size distribution of the metallic particles, D50 is between 3.0 μm and 30.0 μm, and when D90 is the particle diameter with a 90% cumulative frequency in the volume-based particle size distribution of the metallic particles, the D90 / D50 is 2.00 or less, and the volume ratio of the metallic particles having a circularity of 0.60 or less is 2.0% or less.SELECTED DRAWING: Figure 1
