Provided is a method of manufacturing an ultrasound probe. The method includes: preparing a backing layer having first and second surfaces with different heights due to forming a groove in the backing layer, wherein first and second electrodes are exposed on the first and second surfaces, respectively； forming a third electrode that is in contact with the first electrode； forming a base piezoelectric unit on the third electrode, the base piezoelectric unit including a piezoelectric layer； forming a piezoelectric unit by removing an upper region of the base piezoelectric unit； and forming a fourth electrode on the backing layer and the piezoelectric unit.
