An ultrasonic diagnostic apparatus for observing a detectable object to be ultrasonically diagnosed. The apparatus includes an ultrasonically diagnostic probe unit for probing the object with ultrasonic waves in response to input pulse signals and with an ultrasonic echo from the object, a signal transmitting unit to generate the input pulse signals, a signal receiving unit for receiving the ultrasonic echo and processing output signals to be converted into an image of the object, and a display unit to display the image. The ultrasonically diagnostic probe unit comprises an oscillation body having a pair of piezoelectric layers, an intermediate layer sandwiched by the piezoelectric layers, an acoustic lens body operative to focus the ultrasonic waves to be emitted to and reflected by the object, and a supporting body having the oscillation body mounted thereon, thereby making it possible to provide an ultrasonic diagnostic apparatus with a readily machinable oscillation body and to facilitate the machining and adhesive processes of the oscillation body.
