Abstract:
1. A method of producing a magnetic sensor comprising a magnetoresistance effect element that contains a pinned layer and a free layer, said magnetoresistance effect element having a resistance value that changes in accordance with a relative angle formed by a magnetization direction of the pinned layer and a magnetization direction of the free layer, said method comprising the steps of: forming a layer containing a magnetic layer that will become said pinned layer in a predetermined configuration on a substrate; forming magnetic-field-applying magnetic layers for applying a magnetic field to the layer containing the magnetic layer that will become said pinned layer; magnetizing said magnetic-field-applying magnetic layers; and pinning the magnetization direction of the magnetic layer that will become said pinned layer with a magnetic field produced by a residual magnetization of said magnetic-field-applying magnetic layers.
