Abstract
Provided is an amorphous alloy soft magnetic powder having a composition represented by the following formula: (FexCo(1−x))(100−(a+b))(SiyB(1−y)) aMb, [where M is at least one selected from the group consisting of C, S, P, Sn, Mo, Cu, and Nb, 0.73≤x≤0.85, 0.02 ≤y≤0.10, 13.0 ≤a≤19.0, and 0≤b≤2.0], in which a coercive force is 24 [A/m] or more (0.3 [Oe] or more) and 199 [A/m] or less (2.5 [Oe] or less), and a saturation magnetic flux density is 1.60 [T] or more and 2.20 [T] or less.
