Abstract
A soft magnetic alloy including a main component having a compositional formula of (FeX1X2)MBP, and a sub component including at least C, S and Ti, wherein X1 is one or more selected from the group including Co and Ni, X2 is one or more selected from the group including Al, Mn, Ag, Zn, Sn, As, Sb, Bi, and rare earth elements, 'M' is one or more selected from the group including Nb, Hf, Zr, Ta, Mo, W, and V, 0.020≤a≤0.14, 0.020≤b≤0.20, 0≤c≤0.040, α≥0, β≥0, and 0≤α+β≤0.50 are satisfied, when entire said soft magnetic alloy is 100 wt %, a content of said C is 0.001 to 0.050 wt %, a content of said S is 0.001 to 0.050 wt %, and a content of said Ti is 0.001 to 0.080 wt %, and when a value obtained by dividing the content of said C by the content of said S is C/S, then C/S satisfies 0.10≤C/S≤10.
