Summary:PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment capable of reducing noise of a received reflection wave by reducing noise superimposed on a transmission power source in a continuous wave transmission mode.SOLUTION: Ultrasonic diagnostic equipment 100 having a plurality of transmission modes includes: an ultrasonic transducer 10; a transmission circuit 21 for driving the ultrasonic transducer 10 and transmitting an ultrasonic wave; and a power supply unit 30 for supplying a transmission power supply to the transmission circuit 21. The power supply unit 30 switches a controllable range of an output voltage of the transmission power supply according to the plurality of transmission modes. 【課題】連続波送信モードの場合において、送信電源に重畳されるノイズを少なくすることにより、受信する反射波のノイズを低減する超音波診断装置を提供する。【解決手段】複数の送信モードを有する超音波診断装置１００において、超音波振動子１０と、超音波振動子１０を駆動して超音波を送信する送信回路２１と、送信回路２１に送信電源を供給する電源ユニット３０と、を備え、電源ユニット３０は、送信電源の出力電圧の制御可能範囲を、複数の送信モードに応じて切り換える。【選択図】図１
