| Zusammenfassung: | A magnetic field sensor device 1 includes a sensor section 100 that includes a magneto-impedance device 110 having a magnetic amorphous structure, and rod-shaped core sections 130 and 131 that guide a magnetic field to the magnetic amorphous structure in a longitudinal direction with respect to the magnetic amorphous structure. The core sections 130 and 131 may be provided on either side of the magnetic amorphous structure in the longitudinal direction. The core sections 130 and 131 may be disposed so that the longitudinal direction of the magnetic amorphous structure coincides with the longitudinal direction of the core sections 130 and 131. The magnetic field sensor device 1 may include environmental magnetic field cancellation means 140 and 141 that generate a correction magnetic field that cancels the environmental magnetic field input to the magnetic amorphous structure. |
