ABSTRACT:
A shunt biased magnetoresistive element includes a sensor part sensitive to an external magnetic field and a pair of leads (electrodes) in contact with the sensor part. The width (W) of the contact between the sensor part and each of the leads is selected to be equal to or larger than the width (L) of the sensor part. The MR element further includes a center tap having a width (W') selected to be two or more times as large as the width (L) of the sensor part, because the quantity of current flowing through the center tap is two times as large as that flowing through each of the end leads.
