Abstract: The present invention provides a soft magnetic nanowire having a sufficiently high saturation magnetization, a sufficiently high relative magnetic permeability and a sufficiently low coercivity force. The present invention relates to a soft magnetic nanowire, comprising an iron and a boron and having an average length of 5 μm or more and an iron/boron molar ratio in the nanowire of less than 5, wherein the iron/boron molar ratio is measured by a SEM-EDS method.
