1. An optical element driving mechanism, comprising:
a movable portion used for connecting to an optical element, wherein the movable portion comprises a first positioning structure;
a fixed portion comprising a second positioning structure corresponding to the first positioning structure, wherein the movable portion is movable relative to the fixed portion;
a driving assembly used for driving the movable portion to move relative to the fixed portion; and
a circuit assembly electrically connected to the driving assembly and comprises a third circuit element, wherein the third circuit element comprises a first positioning portion and a second positioning portion connected to the movable portion and the fixed portion through the first positioning structure and the second positioning structure, respectively;
wherein the driving assembly is electrically connected to an external circuit through the circuit assembly;
when viewed along the main axis, and before the third circuit element is disposed on the movable portion and the fixed portion, a first gap is between the first positioning structure and the second positioning structure;
when viewed along the main axis, and after the third circuit element is disposed on the movable portion and the fixed portion, a second gap is between the first positioning structure and the second positioning structure;
the first gap and the second gap are different and have a first difference.
