The present invention relates to a soft magnetic alloy and a magnetic part that has high saturation magnetic flux density, a low coercive force, and high magnetic permeability. According to the present invention, the soft magnetic alloy has a composition equation, ((Fe(1-(α +β ))X1α X2β )(1-(a+b+c+e))MaBbPcCue)1-fCf. In this case, X1 indicates one or more selected from the group consisting of Co and Ni, X2 indicates one or more selected from the group consisting of Al, Mn, Ag, Zn, Sn, As, Sb, Bi, N, O and rare earth elements, and M indicates one or more selected from the group consisting of Nb, Hf, Zr, Ta, Mo, W and V.
