MAGNETIC SENSOR MODULE

PROBLEM TO BE SOLVED: To provide a magnetic sensor module that includes a downsizable magnetic sensor, as having high sensitivity.SOLUTION: A magnetic sensor 30 of a magnetic sensor module 20 comprises: a first sensor 40 that includes a first magnetic resistance thin film 424 and a first fixed resistance thin film 444; and a second sensor 50 that includes a second magnetic resistance thin film 524 and a second fixed resistance thin film 544. A resistance value of the first magnetic resistance thin film 424 increases in accordance with increase in magnetic field, and a resistance value of the second magnetic resistance thin film 524 decreases in accordance with the increase in magnetic field. One end side of the first magnetic resistance thin film 424 is connected to one end side of the first fixed resistance thin film 444, and one end side of the second magnetic resistance thin film 524 is connected to one end side of the second fixed resistance thin film 544. The other end of the first magnetic resistance thin film 424 and the other end of the second magnetic resistance thin film 524 are connected to each other, and the other end of the first fixed resistance thin film 444 and the other end of the second fixed resistance thin film 544 are connected to each other.SELECTED DRAWING: Figure 5 【課題】高い感度を有しつつ小型化可能な磁気センサを備える磁気センサモジュールを提供すること。【解決手段】磁気センサモジュール２０の磁気センサ３０は、第１磁気抵抗薄膜４２４及び第１固定抵抗薄膜４４４を含む第１センサ４０と、第２磁気抵抗薄膜５２４及び第２固定抵抗薄膜５４４を含む第２センサ５０とを備えている。第１磁気抵抗薄膜４２４の抵抗値は、磁界の増加に応じて増加し、第２磁気抵抗薄膜５２４の抵抗値は、磁界の増加に応じて減少する。第１磁気抵抗薄膜４２４の一端側は、第１固定抵抗薄膜４４４の一端側と接続されており、第２磁気抵抗薄膜５２４の一端側は、第２固定抵抗薄膜５４４の一端側と接続されている。第１磁気抵抗薄膜４２４の他端側と第２磁気抵抗薄膜５２４の他端側とは、互いに接続されており、第１固定抵抗薄膜４４４の他端側と第２固定抵抗薄膜５４４の他端側とは、互いに接続されている。【選択図】図５
