Abstract:
1. A magnetic force sensor that detects a force on the basis of a position of an action portion and a position of a magnetic flux generating source relative to each other, the action portion being displaceable by the force that the action portion receives, the magnetic force sensor comprising: the action portion resiliently supported by a supporting member; a first magneto-electric transducer fixed to the action portion; the magnetic flux generating source disposed so as to face the first magneto-electric transducer, a position of the magnetic flux generating source being fixed relative to the supporting member; a second magneto-electric transducer disposed at a fixed position with respect to the magnetic flux generating source; and an operational processing section that corrects an output of the first magneto-electric transducer on the basis of an output of the second magneto-electric transducer.
