Abstract
To increase the quality factor Q of the vibrational angular rate sensor and therefore the sensitivity of the sensor, stabilize the sensor performance, facilitate wiring work, and minimize the sensor, a square pillar shaped vibrator, four vibrator node support pins and an external vibrator support base are all formed integral with each other from a single constant elasticity material block. Further, at least three and preferably four piezoelectric elements are connected to an external circuit via at least three and preferably four separate thin film conductive layers each extending from each piezoelectric element, on and along each vibrator node support pin, to an external vibrator support base.
