Abstract
An ultrasonic probe having an electronic radial transducer is disclosed. In the ultrasonic probe, a plurality of piezoelectric elements having electrodes on both surfaces thereof are arranged and juxtaposed on a circular backing member. A doughnut shaped substrate is provided on an end surface of the piezoelectric elements of the electronic radial transducer and having connection points arranged in a signal pattern conductive to one each electrode of the piezoelectric elements. Additionally, at least one overlapping substrate having connection points arranged in accordance with the respective connection points of the signal pattern of the doughnut shaped substrate.
