PROBLEM TO BE SOLVED: To provide a pressure sensor having outstanding noiseproof property uneffected by electrical noises from the outside. SOLUTION: The pressure sensor arranges an insulating member 15 between a metal housing 12, having a built-in sensor chip 11 and a joint housing 14, in order to insulate them electrically; whereas the aforementioned metal housing 12 is electrically connected with stable electric potentials, e.g., any sensor source or a sensor ground.
