PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment generating transmission pulses at a plurality of different voltage levels without increasing the scale of transmission circuits and the number of power supplies. SOLUTION: This ultrasonic diagnostic equipment 1 is provided with a plurality of ultrasonic transducers 3 for transmitting/receiving ultrasonic waves, and a plurality of transmission circuits 2 for actuating the plurality of ultrasonic transducers 3 respectively. The transmission circuits 2 are provided with resistance value variable means SW1, SW2, SW3, SW4, R11, R12, R21 and R22 for varying output resistance values of the transmission circuits 2.
