Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a movable portion, a first driving assembly, and a positioning element. The movable portion is movably disposed on the fixed portion and comprising an optical element. The optical element moves in a first direction. The first driving assembly is at least partially disposed on the fixed portion. The positioning element is rotatably disposed on the fixed portion or the movable portion. When the first driving assembly is not activated, the positioning element is used to limit the position of the movable portion relative to the fixed portion to a limit position, and the positioning element comprises a main body and a limiting portion extending from the main body in a second direction that is perpendicular to the first direction. The limiting portion passes through the optical element.
