Beschreibung
Zusammenfassung:	Disclosed herein is a camera module. The camera module includes a lens barrel having at least one lens which brings an image of a subject into focus. A housing having a space for the lens barrel, and friction member formed in axially. A piezoelectric actuator provided in an outer circumferential surface of the lens barrel, and generating vibration when external voltage is applied to the piezoelectric actuator, with a through hole formed for having the friction member. An elastic member include the friction member, and inserted into the through hole of the piezoelectric actuator, and applying the vibrations to the friction member.
