1. An optical element driving mechanism, having an optical axis, comprising:
a fixed portion, having an opening;
a movable element, which is movable relative to the fixed portion;
a plurality of blades, connected to the movable element;
a driving assembly, driving the movable element to move relative to the fixed portion; and
a circuit assembly, comprising:
a first circuit element, and
a second circuit element, wherein when viewed along the optical axis, the first circuit element and the second circuit element at least partially overlap, wherein the second circuit element comprises a first external connection portion and a second external connection portion,
wherein the first external connection portion and the second external connection portion are used to connect an external circuit,
wherein the first external connection portion has a first metal part,
wherein the second external connection portion has a second metal part,
wherein the first metal part has a first opening;
wherein the second metal part has a second opening;
wherein the first opening and the second opening open in different directions;
wherein the movable element is driven by the driving assembly to change an overlapping area of the blades and the opening.
