A method for producing an ultrasound transducer having piezoelectric or electrostrictive ceramic elements (11) embedded in plastic, with reduced production costs. The ceramic elements (11) are ceramic rods (20) 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 vibrated. The container (31), with the jacketed ceramic rods (20) is filled with a plastic, such as resin or PU. After hardening, the resulting composite body (12) is removed from the container (31), and its top side and/or underside (121, 122) is ground down until the ceramic rods (20) possess a length stipulated by the necessary transducer frequency. Electrodes contacting all or only groups of the ceramic rods (20) are subsequently mounted to the topside and underside (121, 122) of the composite body.
