PROBLEM TO BE SOLVED: To provide a fitting structure of a stem to a housing suitable for smaller scale, related to a pressure sensor where a stem comprising a diaphragm is fixed to a housing into which a pressure is introduced. SOLUTION: A housing 10, comprising a pressure guiding path 13 for guiding a pressure, comprises within it two hollow cylindrical metal stems 20 provided with, on one end side of a shaft, a diaphragm 21 for detecting a pressure and a sensor ship 30 for outputting electric signal corresponding to the deformation of the diaphragm 21 as well as, on the other end side of the shaft, an opening part 22 to communicate with the pressure guiding path 13. A thread part 24 is formed on outer perimeter of each stem 20, and each stem 20 is screw-coupled to the housing 10 while pressurized toward the other end of the shaft, through the thread part 24.
