PROBLEM TO BE SOLVED: To provide a magnetometric sensor which can be constituted of one magnetic sensing unit, as compared with a conventional magnetometric sensor needing two magnetic sensing units. SOLUTION: The magnetometric sensor comprises a Hall element 50, made of a semiconductor thin film or a magnetic thin film, and signal-processing circuits (51, 52, 53, 54, R1, R2) for outputting a tertiary digital signal in response to the level of the detection signal. The sensor outputs the tertiary digital signal, in response to the level of the detected magnetic signal at the output terminal. COPYRIGHT: (C)2003,JPO
