According to an ultrasonic probe using a vertically arranged motor, a motor stands upright in the ultrasonic probe and a side pulley is located in a tangential direction of a probe-shaft pulley, thereby enabling a rotating force generated by the vertically arranged motor to be smoothly transferred to an array axis of ultrasonic elements and significantly simplifying a structure of the ultrasonic probe to remarkably reduce manufacturing costs. In addition, according to the ultrasonic probe using the vertically arranged motor, a mechanism which enables a linear operation is implemented while using the vertically arranged motor. Thus, the ultrasonic probe may have an ergonomic design to significantly improve user satisfaction.
