摘要： A magnetic device comprises a magnetic element, a first magnetic field applying means, and a second magnetic field applying means. The first and second magnetic field applying means are disposed on mutually opposite sides of the magnetic element. The magnetic element is, for example, an element in which a soft magnetic film is formed in a meandering shape on a nonmagnetic substrate. The first and second magnetic field applying means create a magnetic field in one direction from the first magnetic field applying means toward the second magnetic field applying means. The bias magnetic field in one direction is thereby applied to the entire soft magnetic film in the magnetic element disposed between the first and second magnetic field applying means.
