A probe for an electronic scanning type ultrasonic diagnostic apparatus in which a plurality of real transducers and one or more pseudo-transducers are arranged in a row on a supporting plate. In order to equalize the ultrasonic directivity characteristics of each of the real transducers, the pseudo-transducers are arranged adjacent to the real transducers which are located at the ends of the row, and have approximately the same shape and dimensions as the real transducers.

Probe for electronic scanning type ultrasonic diagnostic apparatus

Disclosed is an ultrasonic probe comprising a piezoelectric element in which a first and second electrodes provided respectively on both surfaces of a piezoelectric material are arranged in such a way that said electrodes have end portions facing each other near the center of, and with the interposition of, the piezoelectric material.
