A vibrating reed includes a vibrating body (a base portion, a vibrating arm, and a detection arm) and a support portion that supports the vibrating body via a plate-like coupling portion. In both principal surfaces of the coupling portion, grooves (a first groove and a second groove) are disposed. The first groove arranged in one of the principal surfaces of the coupling portion and the second groove arranged in the other principal surface are arranged at positions different from each other in plan view.
