PROBLEM TO BE SOLVED: To provide a magnetic detector which is relatively compact and low in power consumption and capable of obtaining a magnetic measuring output signal stabilized to environmental variation while keeping high SNR (signal-to-noise ratio).SOLUTION: A magnetic detector comprises: a substrate made of a nonmagnetic material; a magnetism-sensitive element provided on one surface of the substrate; a bulk magnet which is provided on the other surface of the substrate and applies a bias magnetic field to the magnetism-sensitive element; and a soft magnetic structure formed so as to cover at least a part of a magnetic pole of the bulk magnet. |
