The present disclosure provides a probe for an ultrasonic diagnostic apparatus. The probe includes a backing layer, a piezoelectric layer disposed on one side of the backing layer, a matching layer disposed on one side of the piezoelectric layer, a signal connector disposed inside the backing layer to transfer a signal to the piezoelectric layer, and a ground connector disposed outside the signal connector. The backing layer, the piezoelectric layer and the matching layer are sequentially disposed and the signal connector is electrically connected to the piezoelectric layer at the other side of the piezoelectric layer. The probe for an ultrasonic diagnostic apparatus includes a stack of the backing layer, the piezoelectric layer and the matching layer, in which the piezoelectric layer is formed to have a certain curvature, thereby achieving performance improvement through minimization of interference from a signal connector and a ground connector.
