1. An optical element driving mechanism, comprising:
a fixed part;
a movable part, movable relative to the fixed part;
a driving assembly, driving the movable part to move relative to the fixed part; and
a circuit assembly, comprising a photosensitive element holder circuit board,
wherein the movable part comprises a photosensitive element holder, and the photosensitive element holder comprises a photosensitive element holder metal sheet,
wherein the driving assembly comprises a driving magnetic element,
wherein the photosensitive element holder metal sheet at least partially overlaps the driving magnetic element when viewed along an optical axis,
wherein the driving assembly further comprises a driving coil, and the driving coil is disposed between the driving magnetic element and the photosensitive element holder metal sheet,
wherein the photosensitive element holder circuit board is disposed between the driving coil and the photosensitive element holder metal sheet.
