Abstract
A magnetic sensor uses a magnetoresistance element which can be driven in a stable manner with a dipole irrespective of a polarity of an external magnetic field. A resistance value R of first magnetoresistance elements varies, and a resistance value of second magnetoresistance elements does not vary with a variation in magnetic field magnitude of the external magnetic field Hin the positive direction. A resistance value R of second magnetoresistance elements varies and a resistance value of first magnetoresistance elements does not vary with a variation in magnetic field magnitude of the external magnetic field Hin the negative direction. Accordingly, the magnetic sensor can be driven in a stable manner with a dipole irrespective of the polarity of the external magnetic field.
