Abstract
In some embodiments, a magnetic bodyhas soft magnetic alloy grainsthat contain Fe, M (M is a metal element that oxidizes more easily than Fe), and S, as well as oxide filmsproduced by partial oxidization of the soft magnetic alloy grains, wherein the magnetic bodyhas its adjacent soft magnetic alloy grainsbonded together at least partially through the oxide films, and contains Fe by 92.5 to 96 percent by weight and S by 0.003 to 0.02 percent by weight. The magnetic body can have high levels of both magnetic permeability and volume resistivity, to meet the demand for smaller, higher-performance electronic components.
