Abstract

See full text

There is provided a soft magnetic powder in which when a volume-based particle size distribution is measured by a laser diffraction scattering type particle size distribution measuring device, and the particle size distribution is plotted in an orthogonal coordinate system in which a horizontal axis represents a particle diameter and a vertical axis represents a relative particle amount to draw a particle size distribution curve, the particle size distribution curve has a first peak having a local maximum at a particle diameter D1 [μm] and a second peak having a local maximum at a particle diameter D2 [μm] that is larger than the particle diameter D1, the particle diameter D1 is in a range of 1.0 μm or more and 16.0 μm or less, and a difference D2−D1 between the particle diameter D1 and the particle diameter D2 satisfies the following formulas (A-1) and (A-2).
