PURPOSE:To obtain a vibration gyro which is free from influence of change in temperature, etc., which has a vibrator self-vibrated always stably and which can always detect an angular speed with high accuracy, while assembly of the vibrator is easy and reliability can be effectively improved. CONSTITUTION:Piezoelectric elements 12a, 12b adhered to a side of a vibrator 11 having a polygonal lateral cross section are inserted into a positive feedback loop of an amplifier 14. Then connection electrodes of the piezoelectric elements 12a, 12b are connected to an angle speed detecting means 22. |
