Abstract
A driving mechanism for moving an optical element is provided, including a movable portion, a fixed portion, a driving assembly, and a first resilient element. The movable portion is for connecting the optical element. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The first resilient element has a board structure. The movable portion is movably connected to the fixed portion via the first resilient element. The fixed portion includes a connection surface, a restricting surface, and a recessed portion. At least a portion of the first resilient element is disposed on the connection surface. The restricting surface contacts and restricts the movable portion. The recessed portion is located between the connection surface and the restricting surface, wherein the recessed portion is lower than the connection surface and the restricting surface.
