Optical element driving mechanism

An optical element driving mechanism, comprising:

• a fixed portion comprising a case and a base, wherein the case is disposed on the base, and the case comprises a connecting portion directly connected to the base;
• 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;
• 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,
• wherein the connecting portion is positioned between the first driving assembly and the positioning element when viewed in a third direction that is perpendicular to the first direction.
