PROBLEM TO BE SOLVED: To provide a magnetic body core easy to form a terminal electrode, and a coil device including the magnetic body core.SOLUTION: A magnetic body core 2 comprises metal particles 30 isolated by an isolation phase 32. At only a part of the surface of the magnetic body core 2, the isolation phase 32 is removed to form an electrode scheduled portion 20 where the surfaces of the metal particles 30 are exposed within a region of a predetermined area, and terminal electrodes 24, 26 are formed at the electrode scheduled portion 20. |
