An ultrasonic atomizer that is particularly simple to produce and in which desired vibration modes can be excited in a targeted fashion has a piezoelectric vibrator which is formed as a full-area panel and is joined to a substrate panel. The substrate panel is formed with at least one cutout in the form of a through opening. The geometric variables of the hole, such as the length, width, surface area or diameter, are selected in a specific way in order to define the working frequency of the unit with the piezoelectric vibrator and the substrate panel. An ultrasonic atomizer of this type is particularly advantageously used to generate a spray mist for an electric iron.
