Abstract
A soft magnetic alloy contains a main component having a composition formula of (FeX1X2)MBPCand auxiliary components including at least Ti, Mn and Al. In the composition formula, X1 is one or more selected from the group consisting of Co and Ni, X2 is one or more selected from the group consisting of Ag, Zn, Sn, As, Sb, Bi and a rare earth element, and M is one or more selected from the group consisting of Nb, Hf, Zr, Ta, Mo, W and V. In the composition formula, 0.030≤a≤0.100, 0.050≤b≤0.150, 0<c≤0.030, 0<d≤0.030, α≥0, β≥0, and 0≤α+β≤0.50 are satisfied. In the soft magnetic alloy, a content of Ti is 0.001 to 0.100 wt %, a content of Mn is 0.001 to 0.150 wt %, and a content of Al is 0.001 to 0.100 wt %.
