摘要： Disclosed is an ultrasonic transducer which is composed of a plurality of piezoelectric elements having an electrode on each of two opposite surfaces, an acoustic matching layer arranged on the first surface that is one of the two opposite surfaces, a wiring board so arranged on the acoustic matching layer as to be in contact with the piezoelectric element, and a conductor electrically connecting the wiring board with the electrode on the second surface that is one of the two opposite surfaces. This ultrasonic transducer is characterized in that the surface of the wiring board on the same side as the second surface of the piezoelectric element is positioned relatively lower than the second surface of the piezoelectric element.

摘要： The present invention provides an ultrasonic endoscope, comprising: an ultrasonic transducer in a cylindrical shape including a plurality of piezoelectric devices, an acoustic matching layer stacked on a principal plane on a sound emitting plane side, an acoustic lens on a plane of the acoustic matching layer opposite to a plane facing the piezoelectric devices, and a backing material stacked on another principal planes of the piezoelectric devices; an endoscopic observation and endo-therapy unit provided, for performing endoscopic image observation, at a proximal end side of the ultrasonic transducer; a cable ass'y including a plurality of cables for transmitting signals to and from the ultrasonic transducer. In the above configuration, the cable ass'y is arranged in such a manner that the cable ass'y passes through an inside portion of the ultrasonic transducer, and is connected to the ultrasonic transducer at a distal end side of the ultrasonic transducer. Thereby, an ultrasonic endoscope is provided that has an ultrasonic transducer in which the ultrasonic transducer and coaxial cables will not be disconnected even under thermal or mechanical loads.
