Abstract
A vibration device includes a vibration plate, a piezoelectric element, and a wiring member. The vibration plate has conductivity. The piezoelectric element is disposed on the vibration plate. The wiring member is disposed to oppose the vibration plate via the piezoelectric element. The piezoelectric element includes a piezoelectric element body, a first external electrode, and a second external electrode. The piezoelectric element body has a first main surface and a second main surface facing away from each other in an opposing direction of the vibration plate and the wiring member. The first external electrode is disposed on the first main surface and electrically connected to the vibration plate. The second external electrode is disposed on the second main surface and electrically connected to the wiring member. The vibration plate includes a first projection projecting toward the wiring member and electrically connected to the wiring member.
