摘要：
There is provided a soft magnetic powder containing soft magnetic metal particles satisfying the following formulas (A) (B), and (C),
S=k{6/(d·ρ)} (A)
1.0≤k≤4.0 (B)
1.0≤d≤10.0 (C)
in which S [m2/g] indicates a specific surface area, d [μm] indicates an average particle diameter, and ρ [g/cm3] indicates a true specific gravity.
