There is provided a micro piezoelectric actuator, an optical switching device including the micro piezoelectric actuator and a method for fabricating the same. The optical switching device includes a mirror, a first actuator for adjusting the tilt angle of the mirror on the X axis, a second actuator for adjusting the tilt angles of the mirror and the first actuator on the Y axis and a driving substrate for applying a driving signal to the first and second actuators. Each of the actuators has membranes, a piezoelectric device formed on each of the membranes and a connecting part having two elastic bodies coupled to the membranes and a connecting member coupled between the two elastic bodies. In this way, the optical switching device can tilt the mirror on the X axis independently from the tilting thereof on the Y axis.
