ABSTRACT:
A magnetoresistive sensor device including a substrate, and a sensing portion and a signal processing circuit formed above the substrate with a resin film being disposed between the sensing portion and the signal processing circuit. The sensing portion detects changes in a magnetic field induced by a moving body, is located at a position for effectively detecting changes in a magnetic field induced by the moving body, and is constituted by a magnetoresistive sensor element.
