1. An optical component driving mechanism, comprising:
a first holder connecting a first optical component having a first optical axis;
a frame comprising a first accommodating space for accommodating the first holder, wherein the first holder is movable relative to the frame;
a first driving assembly configured to drive the first holder to move relative to the frame;
a first circuit assembly electrically connected to the first driving assembly, wherein the first circuit assembly is electrically connected to the first optical component, the first optical component and the first circuit assembly at least partially overlap when viewed along the first optical axis, and the first circuit assembly is fixedly connected to the first holder; and
a base fixedly connected to the frame, wherein the base is adjacent to the first accommodating space, the base has a metal material;
wherein the base further comprises a stopper portion for limiting the range of motion of the first holder, the stopper portion has a metal material, the stopper portion is located between the first holder and the first circuit assembly when viewed along a first axis perpendicular to the first optical axis;
wherein the stopper portion, the first holder, and the first circuit assembly at least partially overlap when viewed along the first optical axis.
