Abstract
A magnetic body is constituted by grains of a soft magnetic alloy bonded together via an oxide layer, wherein: the soft magnetic alloy is an alloy containing Si by 1 to 5.5 percent by mass, and Cr or Al by 0.2 to 4 percent by mass in total, as constituent elements, with Fe and unavoidable impurities accounting for the remainder; and the oxide layer contains Si, as well as at least one of Cr and Al, where, among Fe, Si, Cr, and Al, Si is contained in the largest quantity based on mass. The magnetic body can have high magnetic permeability.
