Abstract
A magnetic element including: a composite magnetic member A containing a metallic magnetic powder in an amount of 50-70 vol. % and a thermosetting resin in an amount of 50-30 vol. %; a magnetic member B that is at least one selected from a ferrite sintered body and a pressed-powder magnetic body of a metallic magnetic powder; and a coil. The magnetic element is characterized in that a magnetic path determined by an arrangement of the coil passes the magnetic member A and the magnetic member B in series and the coil is embedded in the magnetic member A. The present invention also provides a method for manufacturing the magnetic element.
