PROBLEM TO BE SOLVED: To provide a magnetic detection element enhanced in the detection intensity of a magnetic field of an inspection target substance. SOLUTION: The magnetic detection element has a core consisting of a soft magnetic body, a detection coil for detecting the magnetic field received by the core and an exciting coil for applying an AC magnetic field to the core. Then, the surface of the core in the detection coil is bisected into a first region and a second region in the longitudinal direction of the detection coil and the affinity of the detection target substance is different at least in a part of the first region from in the second region.
