A pressure sensor comprising pressure responsive means wherein its location is shifted in response to variations of a pressure to be detected, and frequency variation means for varying an oscillation frequency of an oscillator in response to a shift movement of the pressure responsive means. The pressure responsive means and the frequency variation means are mounted on a single supporting table. The single supporting table shows a thermal expansion substantially identical with the total thermal expansion of the pressure responsive means and the frequency variation means, thereby stabilizing a pressure detection.
