Abstract
Disclosed is an ultrasonic probe of high performance and high quality. The ultrasonic probe comprises a high molecular material having a conductive layer and is disposed between a piezoelectric element and an acoustic matching layer. The high molecular material has an acoustic impedance substantially equal to that of the acoustic matching layer. The ultrasonic probe thus configured can be formed into a slim shape which is easy to operate without degrading the performance thereof, such as sensitivity or frequency characteristics or the like. The ultrasonic probe is structured so as not to cause an electrical problem due to breakage of wire even if the piezoelectric element is cracked by a mechanical impact or the like, and thus a high quality ultrasonic probe can be provided, and noise can be reduced.
