(57) [Problem] To suppress the fluctuation of the Q value of the vibration detected by a vibrator even when the vibratory gyroscope changes in the environmental temperature when the vibrator is bonded to a support member. To reduce the temperature characteristics of a gyroscope. A vibratory gyroscope includes a vibrator, Support members 31, 31A, 31B for supporting the vibrator 30, 32, 33, and interposed between the support member and the vibrator, An adhesive part (20) for adhering the vibrator to the support member is provided. The rotational angular velocity is obtained from the detected vibration excited by the vibrator according to the rotational angular velocity when drive vibration is applied to the vibrator. The tan δ of the adhesive forming the adhesive portion 20 is 0.1 or less within the operating temperature range of the vibration gyroscope. |
