Abstract: A driving mechanism is provided and configured to drive an optical element. The driving mechanism includes a holding unit, a base unit, an elastic element, a driving assembly, and a sensing assembly. The holding unit holds the optical element. The elastic element connects the holding unit to the base unit. The driving assembly drives the optical element to move relative to the base unit. The sensing assembly is disposed between the holding unit and the base unit for detecting the position of the holding unit relative to the base unit, wherein when observed in an optical axis direction of the optical element, the elastic element and the sensing assembly at least partially overlap.
