Abstract
A soft magnetic powder according to the present disclosure comprises a particle which comprises a plurality of nanosized crystallites and an amorphous phase existing around the crystallites, wherein the crystallites have an average grain diameter of 30 nm or less, and the amorphous phase has an average thickness of 30 nm or less; and wherein when a minor axis of a cross section of the particle is determined as r, an average Fe concentration in the amorphous phase is lower than an average Fe concentration in the crystallites in a region where a depth from a surface of the particle is 0.2 r or more and 0.4 r or less.
