An oscillating element, particularly for a level sensor, comprises an oscillating diaphragm (3), a stack of piezoelectric elements (6, 7), and a tie bolt (4) connected to the diaphragm (3) for pressing the piezoelectric elements (6, 7) against the diaphragm (3). The tie bolt (4) forms a single piece with the diaphragm (3).
