A strain relief apparatus of a probe and a method of manufacturing the same are disclosed. The strain relief apparatus includes an insert part mounted on a probe switch box and having an insertion recess at an inner side thereof, a ferrite core mounted on the insertion recess, and a rubber part provided to the insert part by injection molding. The strain relief apparatus protects a cable of an ultrasonic diagnostic apparatus from impact exerted on the cable and suppresses influence on a contact point between a probe switch box and the cable by bending of the cable, thereby preventing damage of the cable.
