A method for producing an ultrasound transducer having ceramic elements (11) that are embedded in plastic and comprise piezoelectric or electrostrictive ceramic, with the method steps being executed for reducing the production costs. The ceramic elements (11) are produced as ceramic rods (20) that are provided with a plastic jacket (21) of a constant thickness, and the jacketed ceramic rods (20) are organized, while standing upright, in a container (31) that is open on one side and is subjected to vibratory movements. The container (31), with the jacketed ceramic rods (20) is filled with a plastic, such as resin or PU, the resulting composite body (12) is removed from the container (31) after hardening, and its top side and/or underside (121, 122) is or are ground down until the ceramic rods (20) possess a length stipulated by the necessary transducer frequency. Electrodes that contact all or only group of the ceramic rod (20) are subsequently mounted to the topside and underside (121, 122) of the composite body.
