Abstract

Provided are a composite magnetic core with excellent direct current bias current characteristics that is able to use a magnetic powder with poor formability in the desired shape as well as a magnetic element in which a coil is wound around this composite magnetic core. A compressed magnetic object (2) which is obtained by compression molding a magnetic powder and an injection molded object (3) which is obtained by compounding and injection molding a binder resin in a magnetic powder having an electrically insulating surface are press fitted in a joining unit or adhered to each other to obtain a conjugate this conjugate is used as a housing for the injection molded magnetic object and the compressed magnetic object is arranged inside this housing.
