Patent ID: 8453503

Claim:
A resonator element comprising: drive beams including a first beam and a second beam that vibrate in torsional vibration modes and are elongated side by side in a first direction; support parts that couple first ends and second ends of the first beam and the second beam; and detection arms elongated from the respective first beam and second beam in a second direction orthogonal to the first direction in a plan view, wherein, in a drive mode, the first beam and the second beam torsionally vibrate in opposite directions to each other, the respective detection arms vibrate in a normal direction of a plane containing the first direction and the second direction, and the detection arm elongated from the first beam and the detection arm elongated from the second beam vibrate in a same direction as each other, and in a detection mode, when an angular velocity is applied around the second direction, the detection arms vibrate in the first direction.
