<p>Herein disclosed is an ultrasonic diagnostic apparatus for observing a detectable object to be ultrasonically diagnosed. This apparatus comprises an ultrasonically diagnostic probe unit (5) for probing the detectable object (50) with the ultrasonic waves in response to input pulse signals and with the ultrasonic echo from the detectable object (50), a signal transmitting unit (7) operatively connected with the ultrasonic diagnostic probe unit (5) to generate the input pulse signals to be transmitted into the ultrasonic waves (5), a signal receiving unit (8) operatively connected with the ultrasonically diagnostic probe unit (5) for receiving the ultrasonic echo from the detectable object (50) and processing output signals to be converted into the image of the object (50) being observed, a display unit (9) connected with the signal receiving unit (8) to display the image of the object (50) based on the output signals from the signal receiving unit (8) to ensure the ultrasonically diagnosed state of the detectable object (50). The ultrasonically diagnostic probe unit (5) comprises an oscillation body (1) having a pair of piezoelectric layers (11 and 12), an intermediate layer (14) sandwiched by the piezoelectric layers (11 and 12), an acoustic lens body (3) operative to focus the ultrasonic waves to be emitted to and reflected by the object (50d a supporting body (4) having the oscillation body (1) mounted thereon, thereby making it possible to provide an ultrasonic diagnostic apparatus with a readily machinable oscillation body (1) and to facilitate the machining and adhesive processes of the oscillation body (1).
