Abstract: A lens driving module includes a base, a shield can, a driving mechanism, a space maintaining element and a damping element. The base has an opening. The shield can is coupled to the base and has a central aperture corresponding to the opening. The driving mechanism is disposed in the shield and configured to drive a lens unit to move. The space maintaining element is in physical contact with the shield can. The space maintaining element includes a plastic frame portion and a metal structure portion. The metal structure portion includes pins extending toward the base. The metal structure portion is insert-molded with the plastic frame portion to form the space maintaining element. The damping element is connected to the pins and the lens unit. The pins of the metal structure portion are located closer to the optical axis than part of the metal structure portion without the pins.
