Abstract
The present invention provides an optical element driving mechanism. The optical element driving mechanism includes a fixed part, a movable part and a driving assembly. The movable part is movably connected to the fixed part. The movable part includes a holder and a holder stopper. The holder carries the optical element. The holder includes a surface, a sidewall and a holder groove. The sidewall faces the optical element. The holder groove is disposed at the junction of the surface and the sidewall. The holder stopper protrudes from the surface along an optical axis of the optical element to limit a range of motion of the holder. The driving assembly drives the movable part to move relative to the fixed part.
