1. An optical element driving mechanism, comprising:
a first movable part, connected to a first optical element;
a second movable part, connected to a second optical element comprising an optical axis; and
a third movable part, connected to a third optical element;
wherein the first optical element, the second optical element, and the third optical element are arranged along the optical axis,
wherein the second optical element is located between the first optical element and the third optical element when viewed along a direction that is perpendicular to the optical axis,
wherein the second optical element has a second optical element top side and a second optical element bottom side opposite to the second optical element top side,
wherein the second optical element top side faces the first optical element,
wherein the area of the second optical element top side is smaller than the area of the second optical element bottom side.
