An 'ultrasonic diagnostic apparatus' includes: an operating device (1) for an operator to input an instruction; a probe (2) for transmitting and receiving ultrasonic waves; an image display device (3) for displaying an ultrasonic image; and an processing device (4) which drives the probe (1) based on the instruction, produces the ultrasonic image, and displays the image on the image display device (3). The processing device (4) is mounted on an installation platform (5) or placed on a floor (F). A cable receiving space (5a) is provided inside the processing device (5) or the installation platform (5) for receiving a cable (6) of the probe (2). A probe connector (9) is provided above an opening (5b) of the cable receiving space (5a) such that the cable is received into the cable receiving space (5a) in the shape of a U. A movable pulley (10) is hung from a lower end of the U-shaped cable (6), and the movable pulley (10) is supported on a rail (12) in a vertically movable manner.
