MAGNETIC DETECTION DEVICE

This magnetic detection device is provided with a plurality of magnetic sensors each including an excitation coil, a signal coil, and magnetic core layer, a driving circuit, and a detection circuit. A first axis sensor unit is constituted by at least two magnetic sensors out of the plurality of magnetic sensors, the at least two magnetic sensors being each arranged such that a detection direction thereof is aligned with a first axial direction. A second axis sensor unit is constituted by at least one magnetic sensor out of the plurality of magnetic sensors, the at least one magnetic sensor being arranged such that a detection direction thereof is aligned with a second axial direction intersecting with the first axial direction.
