Abstract
A driving mechanism is provided and includes a holder, a frame, a resilient element and a first driving assembly. The holder includes a first holder surface for holding an optical element having an optical axis. The frame is movably connected to the holder and includes a first frame surface. The holder is movably connected to the frame through the first resilient element. The first driving assembly is adjacent to the holder and is used for driving the holder to move relative to the frame, wherein both the first holder surface and the first frame surface face the first resilient element and do not contact the first resilient element, and the shortest distance between the first holder surface and the first resilient element is different than the shortest distance between the first frame surface and the first resilient element.
