Abstract: A lens module comprises a frame, a lens unit, and a driving module for driving the lens unit to move relative to the frame. The lens unit comprises a body made of plastic, at least one lens located in a center of the body, and an embedded member made of metal. The metal embedded member is embedded within a thinner rim portion of the lens unit by means of a plastic insert-molding process in such a manner that, at least one protrusion of the metal embedded member is exposed outside of the rim portion. When the lens unit moves relative to the frame, a location where the lens unit might touch the frame is one of the at least one protrusion, and therefore the structural strength, endure ability of impact and endure ability of friction at the rim portion of the lens unit are increased. In addition, the protrusion can also act as a positioning post or winding post for a coil of the driving module. Or, the coil can also be electrically connected to the protrusion such that the metal embedded member can transmit electric current for the coil.
