Abstract
An ultrasonic transmitting/receiving circuit equipped with: a semiconductor circuit element which comprises at least three terminals including a first terminal connected to a plurality of transducer elements that constitute an ultrasonic probe, a second terminal connected to a transmission signal generating circuit, and a third terminal serving as an output terminal of an amplifier of a reception signal from the transducer element, and which has a function of amplifying a signal inputted from one terminal by the other terminal and outputting the amplified signal between at least two terminals among the above-said three terminals; and a control unit which performs control so as to cause the semiconductor circuit element to perform a first function of functioning as a switch for inputting a transmission signal to the transducer element and a second function of amplifying the reception signal received from the transducer element.
