Abstract
A tuning fork-type vibrator element as a vibrating element includes a drive vibrating arm that performs a flexural vibration, and a drive electrode (a first drive electrode and a second drive electrode) provided on the drive vibrating arm. When a direction in which the drive vibrating arm extends is a Y-axis, a direction in which the drive vibrating arm performs a primary vibration is an X-axis, and a direction orthogonal to the Y-axis and the X-axis is a Z-axis, the drive vibrating arm performs the flexural vibration with a displacement ratio of greater than 0% and 20% or less where the displacement ratio is obtained by dividing a displacement amount in the Z-axis direction by a displacement amount in the X-axis direction.
