Abstract
An imaging lens driving module includes a base, a casing, a driving mechanism and a damping element. The base has an opening, and the casing has a central aperture corresponding to the opening. The casing includes a plastic frame portion and a metal structure portion. The plastic frame portion is coupled to the base. The metal structure portion has a plurality of pins extending towards the base. The driving mechanism is disposed in the casing. The driving mechanism is configured to drive the lens unit to move in a direction parallel to an optical axis. The damping element is connected to the pins and the lens unit. The metal structure portion is insert-molded with the plastic frame portion to form the casing. The pins are located closer to the optical axis than the other part of the metal structure portion to the optical axis.
