The invention provides a soft magnetic alloy including a main component composed of a composition formula (Fe(1-(Alpha+Beta))X1AlphaX2Beta)(1-(a+b+c+d+e+f+g))MaBbPcSidCeSfTig. X1 is one or more of Coand 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 <= 0.0.14 is satisfied. 0.020 < b <= 0.20 is satisfied. 0 <= d <= 0.060 is satisfied. 0 <= f <= 0.010 is satisfied. 0 <= g <= 0.0010 is satisfied. Alpha >= 0 is satisfied. Beta >= 0 is satisfied. 0 <= Alhpa+Beta <= 0.50 is satisfied. At least one or more of f and g are larger than zero. c and e are within a predetermined range. The soft magnetic alloy has a nanohetero structure or a structure of Fe based nanocrystallines. 本发明提供一种提供由组成式(FeX1X2)MBPSiCSTi构成的主成分构成的软磁性合金。X1为选自Co及Ni中的一种以上，X2为选自Al、Mn、Ag、Zn、Sn、As、Sb、Cu、Cr、Bi、N、O及稀土元素中的一种以上，M为选自Nb、Hf、Zr、Ta、Mo、W及V中的一种以上。0.020≤a≤0.14、0.020＜b≤0.20、0≤d≤0.060、0≤f≤0.010、0≤g≤0.0010、α≥0、β≥0、0≤α+β≤0.50。f和g中的至少一个以上大于0。c及e在规定
