A vibration device includes a top plate elastic body, a cylindrical body that includes a first end portion and a second end portion and is coupled with the top plate elastic body to retain the top plate elastic body on a side of the first end portion. The cylindrical body includes on a side of the second end portion, a ring-shaped flange portion extended outward in a radial direction of the cylindrical body, and a piezoelectric element fixed to the ring-shaped flange portion to cause the cylindrical body to vibrate.
