    Abstract: A piezoelectric device includes a vibrator, a piezoelectric drive unit, and a first piezoelectric detector. The vibrator includes a first surface, a first groove formed along a first axis direction, and a second groove formed to be parallel to the first groove. The piezoelectric drive unit includes a first electrode pair provided in the first groove and opposed to each other in a second axis direction orthogonal to the first axis direction and parallel to the first surface, and a first piezoelectric body provided between the first electrode pair, and is capable of vibrating the vibrator. The first piezoelectric detector includes a second electrode pair provided in the second groove and opposed to each other in the second axis direction, and a second piezoelectric body provided between the second electrode pair, and is capable of detecting a vibration of the vibrator.
