Provided is a soft magnetic alloy powder having a component comprising a compositional formula ((Fe (1-(alpha + beta)) Co [alpha] Ni [beta]) (1-gamma) X1 gamma) (1-(a + b + c + d + e)) BaPbSicCdCre (atomic ratio). And X1 represents one or more elements selected from among specific elements. And a-e and alpha-gamma are within specific ranges. And soft magnetic alloy particles. The average value of the circularity of the Wadell of the soft magnetic alloy particles having a particle diameter of (0.95 * D90) or more and (1.05 * D90) or less is 0.75 or more, and the variance of the circularity of the Wadell of the soft magnetic alloy particles having a particle diameter of (0.95 * D90) or more and (1.05 * D90) or less is 0.035 or less. 本发明提供一种具有由组成式((Fe(1-(α+β))CoαNiβ)(1-γ)X1γ)(1-(a+b+c+d+e))BaPbSicCdCre(原子数比)构成的成分的软磁性合金粉末。X1为选自特定的元素中的1种以上。a～e、α～γ在特定的范围内。具有软磁性合金颗粒。粒径为(0.95×D90)以上且(1.05×D90)以下的软磁性合金颗粒的Wadell的圆形度的平均值为0.75以上，粒径为(0.95×D90)以上且(1.05×D90)以下的软磁性合金颗粒的Wadell的圆形度的方差为0.035以下。
