Patent ID: 7808749

Claim:
A magnetic sensor, comprising: a first magnetoresistance effect element, including a soft layer whose magnetization easy direction is changed by a direction of an external magnetic field and a magnetization fixing layer whose magnetization direction is fixed by having a magnetic layer and an anti-ferromagnetic layer, and wherein a magnetoresistance effect of said magnetoresistance effect element is generated by a change of electric conduction which is caused by a relative angle between the magnetization easy direction of the soft layer and the magnetization direction of the magnetization fixing layer, and wherein said magnetization fixing layer has a film surface, and wherein said film surface is not perpendicular to a magnetizing direction; and a second magnetoresistance effect element, including a soft layer whose magnetization easy direction is changed by a direction of an external magnetic field, and a magnetization fixing layer whose magnetization direction is fixed by having a magnetic layer and an anti-ferromagnetic layer, and wherein a magnetoresistance effect of said second magnetoresistance effect element is generated by a change of electric conduction which is caused by a relative angle between the magnetization easy direction of the soft layer of said second magnetoresistance effect element and the magnetization direction of the magnetization fixing layer of said second magnetoresistance effect element, and wherein said magnetization fixing layer of said second magnetoresistance effect element has a film surface, and wherein said film surface of said magnetization fixing layer of said second magnetoresistance effect element is not perpendicular to said magnetizing direction, and wherein said film surface of said magnetization fixing layer of said first magnetoresistance effect element and said film surface of said magnetization fixing layer of said second magnetoresistance effect element are not parallel to each other; and wherein the magnetic sensor has two-axis or more vectors of the magnetization directions, and wherein the magnetoresistance effect elements are adjacently disposed.
