Claim 15:
16. An optical element driving mechanism, comprising:
a movable part, including an optical element holder for connecting an optical element,
wherein the optical element is configured to receive an incident light adjusted by an optical path adjusting unit;
a fixed part, wherein the movable part is movable relative to the fixed part;
a driving assembly, configured to drive the movable part to move relative to the fixed part;
a driving assembly holder, connected to at least a part of the driving assembly; and
a supporting assembly, wherein the movable part is movable relative to the fixed part in multiple dimensions via the supporting assembly,
wherein the driving assembly has a first coil, a second coil, a third coil, a first magnet, and a second magnet,
wherein the first coil and the first magnet are configured to drive the optical element holder to move along a first dimension relative to the driving assembly holder,
wherein the second coil and the second magnet are configured to drive the driving assembly holder to move along a second dimension relative to the fixed part,
wherein the third coil and the first magnet are configured to drive the driving assembly holder to move along a third dimension relative to the fixed part,
wherein the second dimension is parallel to an optical axis of the optical element,
wherein the fixed part includes a frame, a base, and a casing, the casing and the base are arranged along a main axis, and the frame is fixedly arranged on the casing and has a first circuit electrically connected to the driving assembly,
wherein the frame has an extension portion extending toward the base,
wherein when viewed along the main axis direction, the extension portion is located at the corner of the fixed part, and
wherein the first circuit is at least partially buried in the extension portion.
