PROBLEM TO BE SOLVED: To provide: FeSiBNbCu based soft magnetic metal powder for producing a power inductor excellent in the saturation current, the inductance, the magnetic permeability and the core loss value; and a production method of the powder.SOLUTION: In spherical FeSiBNbCu based soft magnetic metal powder, nanocrystal grains are formed. The nanocrystal grains have sizes of 10-20 nm, Wardell's spheroidicity from 0.8 to 1.0 inclusive, and an average grain size from 10 μm to 50 μm inclusive.SELECTED DRAWING: Figure 1 |
