Provided is an ultrasound probe and more particularly, to an ultrasound probe capable of improving the quality of an ultrasound image. The ultrasound probe includes a piezoelectric element unit that transduces an electrical signal and an ultrasound signal in to each other, and a matching layer that is located in front of the piezoelectric element unit to reduce a difference in sound impedance between the piezoelectric element unit and a target object. The piezoelectric element unit may include multiple piezoelectric layers laminated in a forward and backward direction, and each of the multiple piezoelectric layers may have a non-uniform cross-section structure in which a thickness varies in an elevation direction orthogonal to the forward and backward direction.
