To provide a soft magnetic alloy and the like that can be manufactured even with a lower temperature of a molten metal than before and has favorable soft magnetic characteristics.SOLUTION: A soft magnetic alloy includes a composition represented by (FeX1X2)MTiBPSiSC. 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+b≤0.140, 0.001≤b≤0.140, 0.020<c≤0.200, 0.010≤d≤0.150, 0≤e≤0.060, a≥0, f≥0, g≥0, a+b+c+d+e+f+g<1, α≥0, β≥0, 0≤α+β≤0.50 are satisfied. The soft magnetic alloy has a nanohetero structure or a structure of Fe-based nanocrystalline.SELECTED DRAWING: None 【課題】 溶融金属の温度が従来よりも低くても作製可能であり、良好な軟磁気特性を有する軟磁性合金等を提供する。【解決手段】 組成式（Ｆｅ（１−（α＋β））Ｘ１αＸ２β）（１−（ａ＋ｂ＋ｃ＋ｄ＋ｅ＋ｆ＋ｇ））ＭａＴｉｂＢｃＰｄＳｉｅＳｆＣｇで表される組成を有する軟磁性合金である。Ｘ１はＣｏおよびＮｉから選択される１種以上、Ｘ２はＡｌ，Ｍｎ，Ａｇ，Ｚｎ，Ｓｎ，Ａｓ，Ｓｂ，Ｃｕ，Ｃｒ，Ｂｉ，Ｎ，Ｏおよび希土類元素から選択される１種以上、ＭはＮｂ，Ｈｆ，Ｚｒ，Ｔａ，Ｍｏ，ＷおよびＶから選択される１種以上である。０．０２０≦ａ＋ｂ≦０．１４０、０．００１≦ｂ≦０．１４０、０．０２０＜ｃ≦０．２００、０．０１０≦ｄ≦０．１５０、０≦ｅ≦０．０６０、ａ≧０、ｆ≧０、ｇ≧０、ａ＋ｂ＋ｃ＋ｄ＋ｅ＋ｆ＋ｇ＜１、α≧０、β≧０、０≦α＋β≦０．５０である。ナノヘテロ構造またはＦｅ基ナノ結晶からなる構造を有する。【選択図】なし
