An inductor includes a first magnetic substance core which has a middle leg, a first outer leg, a second outer leg, and a body portion interconnecting the middle leg, the first outer leg and the second outer leg, and a second magnetic substance core which is arranged to be opposed to the first magnetic substance core. A first conductor is arranged in a first space which is formed by the middle leg, the first outer leg, part of the body portion, and the second magnetic substance core. A second conductor is arranged in a second space which is formed by the middle leg, the second outer leg, part of the body portion, and the second magnetic substance core. The middle leg is formed with a region which is lower in height than the first outer leg, in the same direction as the longitudinal direction of the first outer leg.

An electromagnetic noise suppressor including a ferrite film is formed by regularly arranging constituents such as magnetized grains or one analogous to that. In the ferrite film, the constituents have at least one of the uniaxial anisotropy and the multiaxial anisotropy. The ferrite film has the magnetic anisotropy or the magnetic isotropy. The ferrite film is formed by a plating method in the presence of a magnetic field.

A ferrite film is formed by regularly arranging constituents such as magnetized grains or one analogous to that. In the ferrite film, the constituents have at least one of the uniaxial anisotropy and the multiaxial anisotropy. The ferrite film has the magnetic anisotropy or the magnetic isotropy. The ferrite film is formed by the use of the plating method in the presence of a magnetic field. Furthermore, an electromagnetic noise suppressor includes the ferrite film.
