The present invention relates to a control panel for use in an ultrasonic diagnostic apparatus, which enables a user to input various commands via one input device, thereby providing convenience in use. The ultrasonic diagnostic apparatus includes a control part for controlling operations thereof and the control panel is configured to transfer an input made by a user to the control part. The control panel comprises: a first input device having a pointing function or a scrolling function; and a second input device disposed around the first input device, the second input device having a plurality of input sections and generating a signal when the user manipulates each input section. A command corresponding to the signal from the second input device is key-mapped by the control part.
