PURPOSE:To improve the measurement efficiency of a pressure sensor by coupling an upper member which has a hole where the output terminal of the pressure sensor is inserted and a lower member which has a hole where pressure to be measured is applied with each other across an O ring. CONSTITUTION:The upper member 10a is provided with the hole Q into which the output terminal 3 of the pressure sensor 1 is inserted, a hole P into which an intake pipe 2 for pressure is inserted, and a conduction pin 13 which abuts on the output terminal 3. Further, the lower member 10b is provided with the hole R into which the pressure to be measured is applied at a position corresponding to the hole P. Then the upper and lower members 10a and 10b are coupled airtightly with each other across the O ring 12. Therefore, when the pressure sensor 1 is measured, a tube 6 need not be connected to the pressure intake pipe 2 at every time and the pressure sensor 1 is merely replaced to measure the sensor with the electric signal at the output terminal 3, thereby improving the measurement efficiency.
