Abstract
In a pressure sensor which has a metal housingcontaining a sensor chipand a joint housingand in which an insulating memberis arranged to electrically insulate both of the metal housingand the joint housingfrom each other, the metal housingis 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.
