ABSTRACT:
A magnetic detection element suitable for detecting a strength of an external magnetic field, has a magnetic thin film formed on a single non-magnetic substrate, a circuit that applies a high-frequency current to the magnetic thin film, and a spiral-type planar coil that is stacked on the magnetic thin film with an insulating layer, in between. The magnetic thin film is formed in a longitudinal shape, and magnetic anisotropy is provided such that the direction of easy magnetization is orthogonal to the longitudinal direction of the longitudinal shape.
