Provided is a magnetic element which exhibits excellent producibility and suppresses heat generation caused by iron loss. A magnetic element provided with a magnetic body though which magnetic flux produced by a coil (4) passes, wherein: this magnetic body is a joined body obtained by joining magnetic bodies to one another which are bisected in the axial direction of the coil; a section exhibiting high heat generation caused by iron loss or a section exhibiting poor heat-dissipation properties constitutes a compression-molded magnetic body (2), while a section other than this compression-molded magnetic body constitutes an injection-molded magnetic body (3); and the compression-molded magnetic body and the injection-molded magnetic body are joined to one another. Furthermore, the compression-molded magnetic body is exposed on the surface of the magnetic body. |
