Abstract: The invention relates to a piezoelectric transducer for generating ultrasound, in particular for ultrasonic cleaning, comprising a vibration plate for transferring of vibrations onto a fluid, and comprising at least one piezo element for generating ultrasound with a one-piece body made of a piezoelectric material having a first surface and a second surface which are arranged essentially parallel to one another and are provided at least in sections with an electrically conductive coating, whereby the piezo element rests with its second surface on the vibration plate and is connected thereto. The electrically conductive coating of the first surface has according to the invention at least two electrodes which are electrically insulated from one another to facilitate application of an operating voltage, and the electrically conductive coating of the second surface is electrically insulated from the first and the second electrodes, and is arranged at least in sections opposite the first and the second electrodes.
