摘要:
A magnetic sensor including a magnetoresistance effect element directed to prevent deterioration in the detection sensitivity occurring due to inversion of the magnetization of a plurality of ferromagnetic thin film stripes forming the magnetoresistance effect element with respect to the initial direction during the repeated operations, the magnetic sensor being arranged in such a manner that the magnetoresistance effect element is disposed at a position deviating from the center of the magnetic pole surface of a cylindrical magnet, preferably at a position deviating in a direction perpendicular to a direction in which the magnetic object to be detected is moved. The thus-employed arrangement enables a bias magnetic field to be applied to the magnetoresistance effect element in parallel to the deviation direction. Therefore, the magnetization of all of the plurality of the ferromagnetic thin film stripes forming the magnetoresistance effect element can be caused to face the same direction. As a result, the detection sensitivity can be stabilized because inversion of the magnetization can be prevented even if external magnetic fields are repeatedly applied.

First electrodes partially configuring light-emitting elements are patterned in the form of stripes on a first major surface of a transparent substrate. After the step of forming the first electrodes, piezoelectric elements functioning a SAW touch sensor is formed on a second major surface of the transparent substrate. Furthermore, after the step of forming the piezoelectric elements, the light-emitting elements forming step of forming light-emitting elements on the first electrodes which are patterned in advance is sequentially executed.Since the first electrodes are formed in the form of stripes, the piezoelectric elements can be prevented from being damaged by an etching solution used at this time. After the formation of the piezoelectric elements, since the step of forming the light-emitting elements is executed, the light-emitting elements can be prevented from being damaged by receiving heat in the formation of the piezoelectric elements.
