A magnetic field detector includes: a magnet; a detecting magnetic resistance element having a layer structure containing a ferromagnetic layer, the resistance being changed when a direction of magnetization of the ferromagnetic layer is changed; and a reference magnetic resistance element having substantially the same layer structure as that of the detecting magnetic resistance element. A magnetic field, the magnetic intensity of which is higher than the saturation magnetic field, is impressed by the magnet in a direction which is sensed by the ferromagnetic layer of the reference magnetic resistance element.
