Title:
MAGNETIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2018/155701
Kind Code:
A1
Abstract:
[Problem] To provide a magnetic sensor that prevents noise from being generated by electromagnetic waves from the outside. [Solution] The present invention comprises: a magnetoresistance effect element 11 that is provided upon a substrate and is connected between ground wiring G and signal wiring S; and magnetic layers 21, 22 that are provided upon the substrate so as to be adjacent to the magnetoresistance effect element 11 and are connected to the ground wiring G. Because the magnetic layers that are adjacent to the magnetoresistance effect element are connected to the ground wiring without touching the signal wiring, noise caused by electromagnetic waves that come in from the outside is not directly superimposed on the signal wiring. In addition, because the magnetic layers are connected to power supply wiring, the noise caused by the electromagnetic waves can be released along the power supply wiring.
