  • Publication number: 20100321143
    Abstract: Provided is an inductor which effectively uses a mounting space and has remarkably reduced radiation noise. The inductor is provided with a magnetic core (1) having a high magnetic permeability, and a coil element (2) integrally embedded in the magnetic core. The magnetic core (1) has a spherical structure, and the coil element (2) has a spherical coil structure wherein a coil conductive wire is spherically laminated. The extracting end of the coil element configures connecting terminals (2a, 2b) by extending to the external of the magnetic core. Since the coil element having the spherical coil structure is integrally embedded inside the magnetic core having the spherical structure, a leaking magnetic flux is remarkably reduced and the magnetic flux is prevented from being disturbed.
