Abstract:
An optical element driving unit includes a stationary body, a carrier, a supporting mechanism and an electromagnetic driving assembly. The supporting mechanism is connected to the carrier and the stationary body and provides the carrier with a degree of freedom of movement relative to the stationary body. The carrier can be driven to move by the electromagnetic driving assembly. The electromagnetic driving assembly includes a driving coil, a driving magnet and a ferromagnetic element. The driving coil is disposed on the carrier. The driving magnet is disposed on the stationary body. The ferromagnetic element is one-piece formed and embedded in the carrier, and the ferromagnetic element includes a magnetic field guiding part and an electrical connection part. The magnetic field guiding part faces the driving coil and/or the driving magnet. The electrical connection part is exposed on a surface of the carrier and electrically connected to the driving coil.
