Summary:A soft magnetic alloy includes a main component of (Fe(1-(α+β))X1αX2β)(1-(a+b+c+d+e))MaBbPcSidCe. X1 is one or more of Co and Ni. X2 is one or more of Al, Mn, Ag, Zn, Sn, As, Sb, Cu, Cr, Bi, N, O, and rare earth elements. M is one or more of Nb, Hf, Zr, Ta, Mo, W, and V. 0.020<a<0.14 is satisfied. 0.020<b<0.20 is satisfied. 0≤d≤0.060 is satisfied. α≥0 is satisfied. β≥0 is satisfied. 0≤α+β≤0.50 is satisfied, c and e are within a predetermined range. The soft magnetic alloy has a nanohetero structure or a structure of Fe based nanocrystallines.
