Vibrating device

A vibrating device comprising:

• a piezoelectric element;
• a wiring board electrically connected with the piezoelectric element;
• and
• a diaphragm including a metal and to which the piezoelectric element and the wiring board are bonded, wherein
• the piezoelectric element includes
• a piezoelectric element body including a piezoelectric material and having a first principal plane and a second principal plane opposed to each other,
• a plurality of internal electrodes disposed in the piezoelectric element body, and opposed to each other in a direction in which the first principal plane and the second principal plane are opposed to each other, and
• a plurality of external electrodes disposed on the first principal plane, and electrically connected with corresponding internal electrodes, of the plurality of internal electrodes,
• the wiring board includes
• a resin film bonded to the diaphragm, and
• a plurality of conductors disposed on the resin film, and electrically connected with corresponding external electrodes, of the plurality of external electrodes,
• the plurality of external electrodes is separated from all of edges of the first principal plane as viewed from the direction, and
• conductors electrically connected with the plurality of internal electrodes are not disposed on the second principal plane of the piezoelectric element body, and the second principal plane and the diaphragm are bonded to each other.
