摘要： A pressure sensor includes a case, a vibrator, a detector, and a processor. The case includes a tubular section and a flat section. The tubular section has a hollow having an opening and is configured to be filled with a target fluid. The flat section closes the hollow. The flat section has a first surface facing the hollow, and a second surface opposite to the first surface. The vibrator is disposed on the second surface of the flat section of the case. The detector outputs a signal according to a vibration of the vibrator. The processor is operable to detect a frequency of the vibration of the vibrator based on the signal output from the detector, and to detect a pressure of the target fluid based on the detected frequency of the vibrator. This pressure sensor has a high sensitivity and excellent characteristics.
