Abstract
A magnetic body constituted by magnetic grains bonded together via oxide film, which magnetic grains contain a Fe—Si-M soft magnetic alloy (where M is a metal element more easily oxidized than Fe) that contains sulfur atoms (S). The magnetic body preferably contains 0.004 to 0.012 percent by weight of S, 1.5 to 7.5 percent by weight of Si, and 2 to 8 percent by weight of metal M.
