1. An optical element driving mechanism, comprising:
a fixed portion;
a movable portion movably disposed on the fixed portion and comprising an optical element, wherein the optical element moves in a first direction;
a first driving assembly at least partially disposed on the fixed portion;
a holder affixed to the optical element and disposed between the optical element and the first driving assembly; and
a positioning element rotatably disposed on the fixed portion or the movable portion, wherein when the first driving assembly is not activated, the positioning element is used to limit a 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, wherein the limiting portion passes through the optical element.
