Abstract

A problem to be solved is to provide a metal powder having a variety of excellent performances, and, in order to solve such a problem, the present invention provides a metal powder that is composed of many spherical particles; that includes at least one of Ni, Fe, and Co, in which the total content (T.C.) of the Ni, the Fe, and the Co is 50 mass % or more; that has a cumulative 10 vol % particle size D10 of 1.0 μm or more; and in which a value Y is 7.5 to 24.0 as calculated by the following mathematical equation: Y=D50×ρ×S, where D50 represents a cumulative 50 vol % particle size of the powder, ρ represents a true density of the powder, and S represents a specific surface area of the powder.
