    • A magneto impedance sensor element with electromagnetic coil comprised of: a terminal board (1) on which an extended groove (11) which extends in one direction has been formed; an electromagnetic coil(3), made with one part of the coil (31) formed in a spiral shape inside the extended groove (11) in the terminal board (1), and joined to each tip of that coil the other part of the coil (32) placed across the top of the groove; insulating material (4) placed in the extended groove (11) on the terminal board(1); and a magnetic sensitive body (2) inserted within the insulating material (4), to which either high frequency or pulse electic current is applied. When either high frequency or pulse electrical current is applied to the magnetic sensitive body, voltage is output from the above electromagnetic coil in response to the intensity of the external magnetic field which is generated in the electromagnetic coil.

    • An MI sensor element 1 includes a substrate 4 formed of a non-magnetic material, a plurality of magneto-sensitive bodies 2, and a plurality of detecting coils 3. The plurality of magneto-sensitive bodies 2 are formed of an amorphous material, and are fixed on the substrate 4, and are electrically connected to each other. The detecting coils 3 are wound around each of the magneto-sensitive bodies 2, and are electrically connected to each other. The MI sensor element 1 outputs a voltage corresponding to a magnetic field strength acting on the magneto-sensitive bodies 2 from the detecting coil 3 by flowing a pulse current or a high-frequency current to the magneto-sensitive body 2. The plurality of magneto-sensitive bodies 2 are formed by fixing one amorphous wire 20 on the substrate 4, and then cutting the wire.
