A vibrating element includes a base, drive vibrating arms, detection vibrating arms, and adjustment vibrating arms. The drive vibrating arms are driven to make bending vibration in a predetermined plane. The following expressions (1) and (2) are satisfied: f3>f2(1) 0.964�(1-0.321(1+L/t))@f2/f1@0.995(2) where t represents the thickness of the base, L represents the length of the base in the direction in which the drive vibrating arms extend, f1 represents the frequency of natural vibration of the detection vibrating arms in a direction that intersects the predetermined plane, f2 represents the frequency of natural vibration of the drive vibrating arms in a direction that intersects the predetermined plane, and f3 represents the frequency of natural vibration of the adjustment vibrating arms in a direction that intersects the predetermined plane. |
