Beschreibung
Zusammenfassung:	There is provided an actuator unit including: a support member supporting a first lens so that the first lens is maintained in a non-contact state with a second lens adjacent thereto; and a piezoelectric member connected to the support member, deforming the support member so that the lenses are movable in an optical axis direction, and including a plurality of piezoelectric elements and a plurality of internal electrodes. The actuator unit configured as described above may improve driving reliability of the lens.
