1. An optical element driving mechanism, comprising:
an optical element, having an optical axis;
a fixed assembly;
a movable assembly, movably with respect to the fixed assembly and configured to hold the optical element; and
a driving assembly, configured to drive the movable assembly to move relative to the fixed assembly,
wherein when viewed along the optical axis, the optical element driving mechanism has a rectangular structure which has a long side and a short side, and a length of the long side is not equal to a length of the short side,
wherein the optical element includes a first section, a second section and a central section disposed between the first section and the second section,
wherein the fixed assembly has a casing opening and a base opening, light travels from a light incident end into the casing opening and the optical element, and the light exits from the base opening to a light exiting end,
wherein when viewed in a direction perpendicular to the optical axis, the first section is protruded from the casing opening, and the second section is protruded from the base opening out of the fixed assembly, and
wherein the first section includes a first lens, the second section includes a second lens, a portion of the first lens is outside of the fixed assembly, and the second lens is totally outside of the fixed assembly.
