The element (1A) for the ultrasonic atomization of liquid is formed around a periphery with steps having edges (A, B, C, D, E) over which a film of liquid flows to be atomized at each edge. To improve the supply of the liquid to the edges (A, B, C, D, E) the edged portion (2A) is provided with liquid supply grooves (20) intersecting the steps. |
