PROBLEM TO BE SOLVED: To provide a sensitivity adjusting method for magnetic sensor modules that can prevent the output of a magnetic sensor module obtained by processing the output of a magnetic sensor element from fluctuating.SOLUTION: By a sensitivity adjusting method for magnetic sensor modules, after forming a magnetic sensor module by modularizing a raw magnet material not yet magnetized and a magnetic sensor element together with an IC for processing the output of the magnetic sensor element, the raw magnet material is fully magnetized by applying a magnetic field, the sensitivity of the magnetic sensor module is figured out from the input magnetic field intensity of a coil and the corresponding output of the magnetic sensor module, then, a magnet is demagnetization-processed, again the sensitivity of the magnetic sensor module is figured out from the input magnetic field intensity of the coil and the corresponding output of the magnetic sensor module, and demagnetization of the magnet is repeated until the sensitivity of this magnetic sensor module reaches a desired level. |
