The angular velocity sensor is provided with a piezoelectric vibrator, a temperature compensation function generating section, a correction coefficient setting section, an oscillation section, a synchronous pulse forming section, and a Coriolis output detection section. If an angular velocity is applied to the piezoelectric vibrator vibrating in a specific direction being driven by the oscillator section, a Coriolis force acts on the piezoelectric vibrator, and a vibration is generated which is perpendicular to the vibration in a specific direction. An electric charge generated by this vibration is detected at the detection electrode of the piezoelectric vibrator. The detected electric charge is converted to a voltage at the Coriolis output detection section, and a temperature compensation is performed, and further, the output is detected and a DC component is extracted. After that, a DC detecting signal having high stability without being influenced by factors such as the ambient temperature, power supply voltage fluctuations and unevenness in circuit devices is output from the Coriolis output detection section.
