ABSTRACT:
A magnetic sensor for detecting an object includes: a detection portion including one half bridge, which has two spin valve type electro-magnetic transformation devices disposed on a substrate; and a magnet near the detection portion having a magnetic field changeable in accordance with influence of the object. The spin valve type electro-magnetic transformation devices are arranged with respect to the magnet in such a manner that a direction of a magnetic field to be applied to one of the spin valve type electro-magnetic transformation devices is opposite to a direction of a magnetic field to be applied to the other one of the spin valve type electro-magnetic transformation devices.
