PROBLEM TO BE SOLVED: To provide a piezoelectric vibration gyro having a temp. dependence of the sensitivity, remaining within specifications even if changing the vibrator material. SOLUTION: In a driving detection circuit of the piezoelectric vibration gyro composed of a differential amplifier 11, coherent detector circuit 12, low- pass filter 13, phase circuit 14 and driving vibration circuit 15, and a resistor used in the phase circuit 11 uses a temp.-sensitive element 19 to thereby reduce the temp. change of the sensitivity of the piezoelectric vibration gyro. |
