<p>A piezoelectric actuator is provided which comprises: a movable member (14) to which a head suspension is fixed; a fixed member (10) fixed to a carriage arm; piezoelectric elements (12) provided between the movable member (14) and the fixed member (10) and capable of adjusting a position of the head suspension (20) by their deformation; and an electrode member (16) electrically connected to one of the electrodes of each of the piezoelectric elements (12). The movable member (14) is adhered on the piezoelectric elements (12) and electrically insulated from the other electrodes of the piezoelectric elements (12). The electric conductive layer of the electrode member (16) and the other electrode of each of the piezoelectric elements (12) are electrically connected to cables, which are provided to the head suspension (20) so as to actuate the piezoelectric elements (12). This provides a small and light piezoelectric actuator which is capable of highly precisely positioning magnetic head assemblies, etc. <IMAGE> <IMAGE></p> |
