A MI sensor element (1) comprises a substrate (4) composed of a non-magnetic material, multiple magnetosensitive bodies (2) and multiple detection coils (3). The multiple magnetosensitive bodies (2) are composed of an amorphous material, are fixed onto the substrate (4), and are electrically connected to each other. The detection coils (3) are respectively twisted around the magnetosensitive bodies (2), and are electrically connected to each other. In the MI sensor element (1), a voltage corresponding to the intensity of a magnetic field that acts on each of the magnetosensitive bodies (2) is output from the corresponding detection coil (3) by applying a pulse current or a high-frequency current to the each of the magnetosensitive bodies (2). The multiple magnetosensitive bodies (2) are formed by fixing a single amorphous wire (20) onto the substrate (4) and then cutting the amorphous wire (20). |
