Abstract

PURPOSE:To prevent an acoustic lens from easily breaking away from an ultrasonic transducer by decreasing the number of adhesive layers, and thus improving the acoustic impedance of the transducer. CONSTITUTION:An ultrasonic transducer 10 is constituted by arranging piezoelectric ceramic materials, which each have electrode layers 12a and 12b on the top and reverse surfaces and cut into strips, on a packing material 14 in parallel and then sticking a single matching layer 15 for a decrease in acoustic impedance over the piezoelectric ceramic materials 13. On the top surface of the transducer 10, silicone rubber and a polyimide layer 16 are formed in one body and an acoustic lens 17 having a polyimide layer on the reverse surface is stuck. This constitution requires only the matching layer 15 consisting of the electrode layers 12b and a glass layer and the two-layered adhesive layer of the matching layer 15 and the polyimide layer 16 of the acoustic lens 17, preventing the evil influence of the adhesives upon acoustic characteristics.
