PROBLEM TO BE SOLVED: To provide a thin-film magnetic-substance MI element in which a change in an impedance can be made large by a low external magnetic field and which can constitute a linear magnetic field sensor without a need of a bias magnetic field in the thin-film magnetic-substance MI element which makes use of a magnetic-impedance effect. SOLUTION: A first magnetic substance 32 and a second magnetic substance 33 are overlapped on a glass substrate, and a film is formed. In addition, the first magnetic substance 32 and the second magnetic substance 33 are constituted in such a way that the easy axis of magnetization Jm1 of the first magnetic substance 32 is set in the direction of an angleαdeg. with reference to a reference line Oo as the passage direction of a high-frequency current Iac, that the easy axis of magnetization Jm2 of the second magnetic substance 33 is set in the direction of an angle -αdeg. and that the easy axis of magnetization Jm1 is crossed with the easy axis of magnetization Jm2.
