An inductor is provided to prevent a leaked magnetic flux from being generated and a magnetic flux from being disturbed by using a magnetic core having a spherical structure. An inductor includes a magnetic core(1) and a coil element(2). The magnetic core has high magnetic permeability. The coil element is integrally embedded in the magnetic core. The magnetic core has a spherical structure. The coil element has a spherical coil structure. A coil conductive wire is spherically stacked. An extracting end of the coil element forms connecting terminals(2a,2b) by extending to an outside of the magnetic core. The coil element having the spherical coil structure is integrally embedded inside of the magnetic core having the spherical structure, thereby remarkably reducing a leaked magnetic flux and preventing the leaked magnetic flux from being disturbed.
