Abstract

A soft magnetic alloy comprising a main component having a compositional formula of ((FeX1X2)MBCr)C, and a sub component including P, S and Ti, wherein X1 is selected from the group Co and Ni, X2 is selected from the group Al, Mn, Ag, Zn, Sn, As, Sb, Bi and rare earth elements, 'M' is selected from the group Nb, Hf, Zr, Ta, Mo, W and V, 0.030≤a≤0.14, 0.005≤b≤0.20, 0<c≤0.040, 0≤d≤0.040, α≥0, β≥0, and 0≤α+β≤0.50 are satisfied, when soft magnetic alloy is 100 wt %, P is 0.001 to 0.050 wt %, S is 0.001 to 0.050 wt %, and Ti is 0.001 to 0.080 wt %, and when a value obtained by dividing P by S is P/S, then P/S satisfies 0.10≤P/S≤10.
