Abstract: A vibrating device includes a vibrating element, a support, and a connector. The vibrating element includes a vibrating body that is tubular and includes a first opening end surface and a second opening end surface. The support extends in an axial direction and supports the vibrating body, the axial direction being a direction connecting the first opening end surface and the second opening end surface of the vibrating body. The connector connects the vibrating body and the support to each other. The vibrating body vibrates in a breathing vibration mode to generate a first node and a second node on the vibrating element at different positions in the axial direction. The connector is positioned between the first node and the second node.

A vibrating beam includes one end portion connected at one location to a fixation member and the other end portion connected at one location to one of the two sides of the weight member in the X-axis direction when looked at in a plan view. The vibrating beam supports the weight member to be displaceable in the X-axis direction. A holding beam includes one end portion connected at one location to the fixation member and the other end portion connected at one location to the other of the two sides of the weight member opposing to each other in the X-axis direction when looked at in a plan view. The holding beam supports the weight member to be displaceable in the X-axis direction. A driver is disposed on the vibrating beam and vibrates the vibrating beam.
