PROBLEM TO BE SOLVED: To stably detect the correct pressure without changing the sensor performance of a sensor chip by inhibiting the transition of the raised temperature of a throttle body via the fitting flange to the pressure sensor. SOLUTION: The pressure sensor P is formed by fitting the sensor housing 3 provided with the sensor chip 5 to the pressure case 4 provided with the pressure port. The fixing flange 9 extending toward one side is integrally formed with the outer periphery 3c of the sensor housing 3, and the fixing flange 9 is extended to the vicinity of the lower end of the pressure case 4 around the outer periphery of the pressure case 4. The base 9a of the fixing flange 9 is formed with the connection base 9a1 connected with the outer periphery of the sensor housing 3 and the non-connected base 9a2 facing to the outer periphery 4b of the pressure case 4 with a clearance. The lower face 9d of the fixing flange 9 is fixed with a thread 11 on the fixing boss 1a. COPYRIGHT: (C)2006,JPO&NCIPI
