In magnetic parts such as inductors and antennas using magnetic metal powder, the complex component of a magnetic permeability, which represents a loss in a GHz band, has been high. n A magnetic part formed from a soft magnetic metal powder including iron as a main component can reduce a loss factor in a kHz to GHz band. The soft magnetic metal powder has an average particle diameter of 100 nm or less, an axial ratio (=major axis length/minor axis length) of 1.5 or more, a coercive force (Hc) of 39.8 to 198.9 kA/m (500 to 2500 Oe), and a saturation magnetization of 100 Am 2 /kg or more. |
