Abstract
A magnetic field sensor deviceincludes a sensor sectionthat includes a magneto-impedance devicehaving a magnetic amorphous structure, and rod-shaped core sectionsandthat guide a magnetic field to the magnetic amorphous structure in a longitudinal direction with respect to the magnetic amorphous structure. The core sectionsandmay be provided on either side of the magnetic amorphous structure in the longitudinal direction. The core sectionsandmay be disposed so that the longitudinal direction of the magnetic amorphous structure coincides with the longitudinal direction of the core sectionsand. The magnetic field sensor devicemay include environmental magnetic field cancellation meansandthat generate a correction magnetic field that cancels the environmental magnetic field input to the magnetic amorphous structure.
