Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed part, a movable part, and a driving assembly. The fixed part includes a bottom. The movable part moves relative to the fixed part and holds an optical element with an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The bottom includes a base and an embedded assembly. A portion of the embedded assembly is embedded in the base. The embedded assembly includes a circuit member and a strengthening frame with a plate structure. The strengthening frame includes a perforation. The optical axis passes through the perforation.

Abstract: A lens driving module is provided, configured to drive an optical element, including a holder, a circuit board assembly, a base module, and a magnetic element. The optical element is disposed in the holder, and the circuit board assembly has a driving coil. The base module has a metal substrate, an insulating layer, a circuit layer electrically connected with the driving coil, and a protective layer. The metal substrate has a bent portion where an opening is formed on. A wire of the circuit layer extends across the opening and forms a bridging portion. The protective layer has a protruding portion extending over the opening and covers the bridging portion. The magnetic element is coupled to the driving coil, and the two are configured to drive the optical element to move relative to the base module.
