Abstract
An array-type ultrasonic probe for an ultrasonic transducer has a basic structure comprising a substrate on which are successively disposed a plurality of parallel stripe form back electrodes, a polymer piezoelectric film and a front electrode. One end of each stripe-form back electrode is made thin, bent along the side wall of the substrate and connected to a lead wire from the ultrasonic transducer. Such a connection structure allows a tight arrangement of the back electrodes while avoiding contact between the electrodes, thus providing a high resolution to the ultrasonic probe.
