摘要 |
There are provided a tuning fork vibrator (10) well-balanced in between legs, a vibrating gyroscope using the vibrator, an electronic apparatus using the vibrator, and a manufacturing method of the vibrator. A tuning fork vibrator (10) includes a long plate-like vibration unit (13) having one principal surface and the other principal surface, a base (14) disposed at one end of the other principal surface of the vibration unit in the longitudinal direction, and a slit (15) for dividing the vibration unit into two legs (16,17) constituting a tuning fork along the longitudinal direction symmetrically in the width direction of the vibration unit (13). The slit is formed so as to include a portion of the base close to the vibration unit. <IMAGE> |
