Abstract

PURPOSE:To obtain a transducer adequate for a high-frequency range and also to simplify weighting by forming a metal thin-film electrode on one surface of a piezoelectric film and electrodes with a slit on the other. CONSTITUTION:On the nearly-entire surface of substrate 1 of glass, etc., metal thin- film electrode 10 is formed by vapordeposition. On this metal thin-film electrode 10, piezoelectric film 11 of zinc oxide, cadmium sulfide, etc., is formed by sputtering. On piezoelectric film 11, electrodes 12A and 12B with a slit are formed by photoetching. One terminal of metal thin-film electrode 10 and slit elecrode 12A are connected to input terminals 5A and 5B respectively, and the other terminal of electrode 10 and slit electrode 12B are to output terminals 9A and 9B.
