MAGNETIC SENSOR AND METHOD FOR MANUFACTURING THE MAGNETIC SENSOR

PROBLEM TO BE SOLVED: To provide a magnetic sensor that demonstrates a high level of reliability as a whole if a main sensor breaks down due to a large environmental load applied on the magnetic sensor.SOLUTION: The magnetic sensor includes a first magnetic sensor element and a second magnetic sensor element different in type from the first magnetic sensor element. The first and second magnetic sensor elements have the same measurement target space region, the first magnetic sensor element exhibits a higher performance than the second magnetic sensor element does with respect to the first characteristic, and the second magnetic sensor element exhibits a higher performance than the first magnetic sensor element does with respect to the second characteristic different from the first characteristic.SELECTED DRAWING: Figure 2 【課題】過大な環境負荷が磁気センサに加わり、主系統のセンサが故障するような場合であっても、全体として高い信頼性を示す磁気センサを提供する。【解決手段】第１磁気センサ素子と、前記第１磁気センサ素子とは種類が異なる第２磁気センサ素子と、を有し、前記第１磁気センサ素子および前記第２磁気センサ素子の測定対象空間領域が同じであり、第１特性における前記第１磁気センサ素子の性能が、前記第２磁気センサ素子より高く、前記第１特性とは異なる第２特性における前記第２磁気センサ素子の性能が、前記第１磁気センサ素子より高い磁気センサを提供する。【選択図】図２
