摘要： PROBLEM TO BE SOLVED: To provide a magnetic detection element that eliminates the cause of errors due to temperature characteristic by reducing the influence to inductance and impedance caused by the movement of a magnetic domain wall, as much as possible, and at the same, time reduces impedance characteristics monotonously to the increase of a magnetic field.
SOLUTION: The magnetic detection element has a rectangular thin-film magnetic material layer 15, and a conductive material 14 which is continuous to the magnetic material layer 15. In this case, by supplying a high-frequency current along the longitudinal direction of the magnetic material layer 13, magnetic anisotropy along the longitudinal direction of the magnetic material layer 15 is added to the magnetic material layer 15 of a magnetic detection element 10 for detecting change in electrical characteristics corresponding to an external magnetic field.
