ABSTRACT:
In a pressure sensor which has a metal housing12containing a sensor chip11and a joint housing14and in which an insulating member15is arranged to electrically insulate both of the metal housing12and the joint housing14from each other, the metal housing12is connected to a stable potential such as, for example, a sensor power supply or a sensor ground. Thus, there can be solved a problem that the detection signal is liable to be influenced by electric noise from outside where a signal line of the pressure sensor and the sensor housing are electrically suspended or unfixed.
