A lens module includes a case, one and more lens units positioned in the case and having at least one lens, a carrying member, a piezoelectric driving unit, and at least a fixing member. The carrying member is connected to the lens unit such that the lens unit is movable forward and backward. The piezoelectric driving unit is mounted in the case for transferring a driving force to the carrying member so as to carry the lens unit to move. By using this configuration, the front and rear lens units may conduct the auto focus function and the zoom function respectively, thereby reducing a stroke of the lens, and reducing the size of the lens driving unit. Accordingly, the lens module may be manufactured in a small size so that it may be inserted into a cellular phone.
