Abstract
In some embodiments, a magnetic body 1 has soft magnetic alloy grains 11 that contain Fe, M (M is a metal element that oxidizes more easily than Fe), and S, as well as oxide films 12 produced by partial oxidization of the soft magnetic alloy grains 11, wherein the magnetic body 1 has its adjacent soft magnetic alloy grains 11 bonded together at least partially through the oxide films 12, 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.
