A method for producing an ultrasonic test head having an ultrasonic transducer arrangement ( 200 ) with a curved transceiving surface ( 23 ) that is constructed from a plurality of juxtaposed transducer elements ( 14 ), comprises in accordance with the invention the following method steps: a) a piezoelectric planar plate ( 2 ) corresponding to the external dimensions of the ultrasonic transducer arrangement is bonded with one of its flat sides ( 2 a) on to a film ( 4 ) made from a polymer, b) introduced into the flat side ( 2 b), averted from the film ( 4 ), of the piezoelectric plate ( 2 ) before or after the bonding on to the film ( 4 ) are grooves ( 12 ) whose depth corresponds at least approximately to the thickness of the plate ( 2 ) such that a planar ultrasonic transducer arrangement ( 20 ) is produced that consists of a plurality of juxtaposed transducer elements ( 14 ), and c) the planar ultrasonic transducer arrangement ( 20 ) is subsequently mounted with its flat side ( 2 a) bonded to the film ( 4 ) on a curved bearing surface of a bending device ( 22 ) and bent there into a curved shape.
