Stage: PROBLEM TO BE SOLVED: To provide a magnetic complex body that has an excellent reliability and that can be used for a long time period with stability, and to provide an element or component with a coil and/or inductor function, an electronic device, a housing for housing electronic components, an electromagnetic wave absorber, an electromagnetic wave shield, or an element or component with an antenna function that comprise such the magnetic complex body.SOLUTION: A magnetic complex body comprises a base material, and a ferrite layer provided on a surface of the base material. The ferrite layer includes a first ferrite phase with a spinel type crystal structure and a second ferrite phase with a spinel type crystal structure as different phases. Each of the first and second ferrite phases contains iron (Fe) and oxygen (O), and further contains at least one kind of element selected from a group consisting of lithium (Li), magnesium (Mg), aluminum (Al), and transition metal elements other than iron (Fe). The composition of the second ferrite phase is different from that of the first ferrite phase.SELECTED DRAWING: Figure 8 (Grant)
