PROBLEM TO BE SOLVED: To resolve a problem of a high magnetic permeability complex-number component, which is related to a loss in the GHz band, in magnetic parts such as inductors and antennas using metal magnetic powder.SOLUTION: A loss coefficient in the kHz-GHz band can be made low by a magnetic part formed from a metal powder that is a soft magnetic metal powder with iron as a major component thereof, said metal powder being characterized by an average particle diameter of 100 nm or less, an axis ratio (i.e., long axis length/short axis length) of 1.5 or more, a coercivity (Hc) of 39.8-198.9 kA/m (500-2500 Oe), and a saturation magnetization of 100 Am/kg or more. |
