ABSTRACT:
A tuning-fork vibration gyro including a ferroelectric tuning-fork vibration body generating a plurality of sensor signals and a sensor circuit to which the sensor signals generated by the tuning-fork vibration body are input. The sensor circuit includes a differential amplifier having two input terminals between which the sensor signals are input, and a capacitor being connected between the two input terminals of the differential amplifier.
