(57) Abstract: Provided are a magnetic thin film having sufficient soft magnetic characteristics and high electric resistivity, and a magnetic element having such a magnetic thin film. A magnetic thin film of the present invention has a composition formula (Fe Magnetic materials (in the formula represented by 1-α Co α) 1- β (B 1-χ -δ N δ X χ) β, α, β, respectively chi and [delta] satisfies the following inequality, X is a Group 4B element, Is shown). 0 <α <1, 0.05 ≦ β ≦ 0.55, 0 ≦ χ <1, 0 <δ <1, χ + δ <1 |
