PROBLEM TO BE SOLVED: To provide a vibrator capable of easily canceling an angular velocity signal or an acceleration signal detected even in a state in which an angular velocity or acceleration is not added to a sensor element.SOLUTION: A vibrator comprises: a base; a detection arm extending from the base; a first connection part extending in a direction crossing an extension direction of the detection arm from one end of the base; a second connection part extending in a direction crossing the extension direction of the detection arm from the other end of the base; a first vibration arm extending in a direction crossing an extension direction of the first connection part from the first connection part; and a second vibration arm extending in a direction crossing an extension direction of the second connection part from the second connection part. The first and second connection parts include a piezoelectric part.
