Abstract
A tuning bar vibrator formed on a substrate and including a vibrating body. The vibrating body is formed into a meander shape as a whole, and a middle vibrating reed is used as a first detection unit. At one end side of the vibrating body, two sensing electrodes are formed and connected respectively to two extended electrodes. A further sensing electrode and a common electrode are formed on a first principal surface of the first detection unit. A common electrode formed on a second principal surface of the vibrating body is connected to the common electrode on the first principal surface via a through-hole. The further sensing electrode and the common electrode are connected respectively to another set of extended electrodes. A tuning bar vibrator that is small in size, may be reduced in profile and may be used as a vibrating gyroscope having a desirable detection sensitivity, and a vibrating gyroscope using the tuning bar vibrator are obtained.
