Abstract
A soft magnetic alloy which includes nanocrystal parts and amorphous parts is provided. The nanocrystal parts include αFe(—Si) as a main component, and include at least one of elements selected from B, P, C, Ti, Zr, Hf, Nb, Ta, Mo, V, W, Cr, Al, Mn, Zn, and Cu as a sub-component. When a total content ratio of the sub-component in the nanocrystal parts is set as α (at %), and a total content ratio of the sub-components of the nanocrystal parts included in the amorphous parts is set as β (at %), 0.01≤(α/β)≤0.40, and a crystallinity degree is 5% or more and 70% or less.
