ABSTRACT:
A physical quantity sensor detects physical quantity. The sensor includes a plurality of springs, which have different spring constants, respectively. The sensor has a wide detection range of the physical quantity without assembling multiple sensors. Therefore, the sensor can be minimized. Further, since the sensor has an excellent linearity of the output characteristics, the sensor has a wide dynamic range and a high sensitivity.
