A piezoelectric actuator is provided which acts as a micromechanical actuating element. Thus, the piezoelectric actuator has a piezoelectric element and an electrode structure, wherein said electrode structure is arranged with the electrodes thereof exclusively on one side of the piezoelectric element. Furthermore, the piezoelectric actuator has at least one attachment element, wherein the attachment element is fitted on the piezoelectric element and on the side of the electrode structure of the piezoelectric element, and the attachment element at least partially encompasses the electrode structure of the piezoelectric actuator. The attachment element in the process, by virtue of encompassing the electrode structure, provides a physical limit for the expansion of the piezoelectric element.
