Abstract
To increase, in a magnetic sensor having a magnetoresistive strip and a ferromagnetic film, a magnetic bias to be applied to a magnetoresistive element by magnetically coupling the magnetoresistive strip and ferromagnetic film. A magnetic sensorincludes a magnetoresistive strip S, an insulating filmthat covers the magnetoresistive strip S, and ferromagnetic films Mand Mformed on the insulating filmand arranged in the x-direction through a magnetic gap G extending in the y-direction. The ferromagnetic films Mand Moverlap a plurality of hard magnetic members H through the insulating film. This allows two adjacent hard magnetic members H to be magnetically coupled through the ferromagnetic films Mand M. This makes it possible to increase the magnetic bias to be applied to a magnetoresistive element R without involving an increase in the size of the hard magnetic member H.
