| description | A vibrating device includes a piezoelectric element, a wiring board electrically connected with the piezoelectric element, and a diaphragm including a metal. The piezoelectric element and the wiring board are bonded to the diaphragm. The piezoelectric element includes a piezoelectric element body, a plurality of internal electrodes, and a plurality of external electrodes. The piezoelectric element body has a first principal plane and a second principal plane opposed to each other. The plurality of internal electrodes is disposed in the piezoelectric element body. The internal electrodes are opposed to each other in a direction in which the first principal plane and the second principal plane are opposed. The plurality of external electrodes is disposed on the first principal plane, and is electrically connected with corresponding internal electrodes, of the plurality of internal electrodes. The wiring board has a resin film and a plurality of conductors. |
