To provide a vibratory gyroscope capable of detecting a change in posture with high accuracy without causing leaking of vibrations of vibrating bars via supporting units, a vibrator includes first to fourth vibrating bars extending parallel to each other substantially in the same plane, a bar-shaped beam extending substantially perpendicular to the four vibrating bars in the same plane and connected to the vibrating bars, bar-shaped supporting units to support the beam, driving units arranged in the third and fourth vibrating bars, and a detecting unit arranged the first vibrating bar.
