Sintering metal powder

Abstract

A sintering metal powder, in which a particle size distribution curve has a first peak having a maximum value at a particle diameter D1 [μm] and a second peak having a maximum value at a particle diameter D2 [μm] which is larger than the particle diameter D1, where the particle size distribution curve is drawn by measuring a volume-based particle size distribution of the sintering metal powder with a laser diffraction scattering particle size distribution measurement device, and plotting the particle size distribution on an orthogonal coordinate system in which a horizontal axis is a particle diameter and a vertical axis is a relative particle amount. The particle diameter D2 is 30.0 μm or less, a height of the second peak is 0.60 or more and 3.00 or less when a height of the first peak is 1, and an average degree of circularity calculated from a captured image is 0.70 or more and 1.00 or less.
