摘要

To provide a soft magnetic powder capable of forming a powder magnetic core, of which oxygen amount is reduced even though particle diameter is small and magnetic permeability is high.SOLUTION: There is provided a soft magnetic powder constituted by an Fe alloy containing Si, containing of 0.1 mass% to 15 mass%, and a product of D50, which is cumulative 50% particle diameter [μm] based on volume, measured by a laser diffraction type particle size distribution measurement device and [O], which is content of oxygen [mass%], (D50×[O]) of 3.0 [μm mass%] or less.SELECTED DRAWING: Figure 1
