    Abstract: An optical element driving mechanism is provided in the present disclosure, including a first movable portion, a fixed portion, a first driving assembly and a first supporting assembly. The first movable portion is connected to a first optical element. The first movable portion is movable relative to the fixed portion. The first driving assembly drives the first movable portion to move relative to the fixed portion in a first dimension. The first supporting assembly is disposed between the first movable portion and the fixed portion. The first movable portion moves relative to the fixed portion via the first supporting assembly.

    Abstract: An optical module is provided. The optical module includes a first optical element driving mechanism. The first optical element driving mechanism includes a first movable portion, a first fixed portion, and a first driving assembly. The first movable portion connects an optical path adjustment element. The optical path adjustment element is configured to change a transmission direction of incident light to a first direction that is different from the transmission direction. The first fixed potion is polygonal when viewed in the transmission direction. The first movable portion is movable relative to the first fixed portion. The first driving assembly drives the first movable portion to move relative to the first fixed portion. The first driving assembly comprises a shape memory alloy. The first driving assembly is located on a first side of the first fixed portion when viewed in the transmission direction.

    Abstract: A camera module is provided, including a lens driving mechanism, a lens unit, a circuit board, and an image sensor. The lens unit is disposed on the lens driving mechanism. The image sensor is disposed on the circuit board. The circuit board includes a metal member, an insulation layer, and a metal wire. The insulation layer is disposed between the metal member and the metal wire, and the metal wire is electrically connected to the image sensor. The lens driving module can drive the lens unit to move relative to the image sensor. The image sensor can catch the light through the lens unit.

    Abstract: A lens driving device is provided, including a frame, a lens holder, and a dust-proof structure. The frame includes a top casing and a bottom base. The lens holder carries a lens and is movably disposed in the frame and has a first anti-twist structure. A second anti-twist structure corresponding to the first anti-twist structure is formed on a surface of the bottom base. The dust-proof structure is formed on the surface of the bottom base to prevent dust from entering a receiving hole in the bottom base, and the receiving hole is used for receiving an image sensor.
