Abstract:
A magnetic detection element, comprises a core composed of a soft magnetic material, a detecting coil for detecting a magnetic field applied to the core, and an exciting coil for applying an alternating magnetic field to the core, wherein the surface of the core is divided into a first region and a second region in the longitudinal direction of the detecting coil, the first region and the second region being different in affinity for a detection object substance.
