PROBLEM TO BE SOLVED : To provide a soft magnetic alloy simultaneously having high saturation magnetic flux density, low coercive force, and high magnetic permeability. SOLUTION : The soft magnetic alloy comprises a main component represented by compositional formula : ((Fe(1-(α+β))X1αX2β)(1-(a+b))MaBb)1-cCc as a main component and an accessory component containing at least P, S and Ti. (X1 is one or more selected from Co and Ni; X2 is one or more selected from Al, Mn, Ag, Zn, Sn, As, Sb, Bi and rare earth elements; M is one or more selected from Nb, Hf, Zr, Ta, Mo, W and V; 0.030≤a≤0.14; 0.005≤b≤0.20; 0≤c≤0.040; α≥0; β≥0; and 0≤α+β≤0.50.) The content of P is 0.001-0.050 wt.%, the content of S is 0.001-0.050 wt.%, the content of Ti is 0.001-0.080 wt.%, and 0.10≤P/S≤10 is satisfied. SELECTED DRAWING : None COPYRIGHT : (C)2018, JPO&INPIT
