An Fe-based soft magnetic alloy having a high saturated magnetic flux density and having a composition represented by formula (I) below: (Fe1-a Q a)b B x T y T'z (I) wherein Q represents at least one element selected from the group consisting of Co and Ni: T represents at least one element selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, Mo and W, with Zr and/or Hf being always included; T' represents at least one element selected from the group consisting of Cu, Ag, Au, Ni, Pd and Pt: a, b, x, y and z are real numbers satisfying relationships below: 0 ~ a ~ 0.05 atomic %, 0 < b ~ 93 atomic %, 0.5 ~ x ~ 16 atomic %, 4 ~ y ~ 10 atomic %, 0 ~ z ~ 4.5 atomic % provided that when 0 < z ~ 4.5 atomic %, Q represents Co and 0 < b ~ 92 atomic %: and when z = 0, 0.5 ~ x ~ 8 atomic % and 4 ~ y ~ 9 atomic %. Soft magnetic materials such as thin film, ribbon and powder compact made of the alloy, magnetic transducers such as low frequency transformers and magnetic heads using the material and processes and apparatuses for producing ribbons.
