To provide a soft magnetic alloy that contains Co, and has higher saturation magnetic flux density Bs and does not significantly increase coercive force Hc as compared with the case that does not contain Co.SOLUTION: There is provided a soft magnetic alloy that is made up of a compositional formula (Fe(1-(α+β+γ))CoαNiβXγ)(1-(a+b+c))MaCbX3c (atomic ratio). X is one or more selected from a group consisting of Al, Mn, Ag, Zn, Sn, As, Sb, Cu, Cr, Bi, Ca, Mg, Ti, Na, N, V, Mo, O, S and rare earth elements, M is one or more selected from a group consisting of Ta, Zr, Hf, Nb and W, and X3 is one or more selected from a group formed of P, B, Si and Ge, in which, a-c and α-γ are in a prescribed range.SELECTED DRAWING: Figure 1 【課題】Ｃｏを含む軟磁性合金であって、Ｃｏを含まない場合と比較して高い飽和磁束密度Ｂｓを有し保磁力Ｈｃが大きく上昇しない軟磁性合金を提供する。【解決手段】 組成式（Ｆｅ（１－（α＋β＋γ））ＣｏαＮｉβＸγ）（１－（ａ＋ｂ＋ｃ））ＭａＣｂＸ３ｃ（原子数比）からなる軟磁性合金である。ＸはＡｌ，Ｍｎ，Ａｇ，Ｚｎ，Ｓｎ，Ａｓ，Ｓｂ，Ｃｕ，Ｃｒ，Ｂｉ，Ｃａ，Ｍｇ，Ｔｉ，Ｎａ，Ｎ，Ｖ，Ｍｏ，Ｏ，Ｓおよび希土類元素からなる群から選択される１つ以上、ＭはＴａ，Ｚｒ，Ｈｆ，ＮｂおよびＷからなる群から選択される１つ以上、Ｘ３はＰ，Ｂ，ＳｉおよびＧｅからなる群から選択される１つ以上である。ａ～ｃ，α～γが所定の範囲内である。【選択図】図１
