Abstract: A tuning fork vibrator includes a long plate-shaped vibration unit having a first principal surface and a second principal surface, a base disposed at one end of the second principal surface of the vibration unit in the longitudinal direction, and a slit for dividing the vibration unit into two legs defining a tuning fork along the longitudinal direction symmetrically in the width direction of the vibration unit. The slit is formed so as to include a portion of the base in the vicinity to the vibration unit.
