Abstract
An ultrasonic transducer comprising, a piezoelectric block which is formed into a plurality of piezoelectric segments by way of one or more slots, spaced apart, on one main surface of the block, the segments being connected with each other at one and the other of the opposed main surfaces of the block, an organic filler filled at least partially in the slots, a first and a second electrodes formed respectively on the one and the other of the continuous main surfaces of the segments, an acoustic matching layer formed on the one main surface of the piezoelectric block, and a backing material formed on the other main surface of the piezoelectric block.
