A piezoelectric actuator in which at least on piezoelectric element is present for subjected an actuating element to a tensile force or compressive force. In addition, stabilizing elements are mounted parallel to the piezoelectric element with a flexible intermediate layer located between the elements. The piezoelectric element and the stabilizing elements have a great length in the effective direction (Z axis) in proportion to their width transversely to the effective direction (X, Y direction).
