1. An optical element driving mechanism, comprising:
a movable part, for connecting an optical element;
a fixed part, wherein the movable part is movable relative to the fixed part;
a driving assembly, for driving the movable part to move relative to the fixed part; and
a first supporting assembly, wherein the movable part is movable relative to the fixed part through the support of the first supporting assembly,
wherein the movable part comprises a movable part setting surface, and the movable part setting surface corresponds to the optical element;
wherein the driving assembly comprises:
a first coil assembly;
a second coil assembly; and
a driving assembly substrate, wherein when viewed along a direction that is perpendicular to a thickness of the driving assembly substrate, the first coil assembly and the second coil assembly are located at opposite sides of the driving assembly substrate,
wherein the driving assembly substrate comprises:
a driving assembly substrate body, having a metal material;
a first insulating layer, located between the driving assembly substrate body and the first coil assembly; and
a second insulating layer, located between the driving assembly substrate body and the second coil assembly,
wherein when viewed along a thickness direction of the driving assembly substrate, the optical element does not overlap the first insulating layer,
wherein when viewed along the thickness direction of the driving assembly substrate, the optical element at least partially overlaps the second insulating layer.
