Abstract: An imaging lens module with auto focus function includes an imaging lens assembly, an electromagnetic driving component assembly and a lens carrier. The imaging lens assembly has an optical axis. The electromagnetic driving component assembly drives the imaging lens assembly to move in a direction parallel to the optical axis by a Lorentz force. The imaging lens assembly is mounted to the lens carrier such that the imaging lens assembly can be wholly driven by the Lorentz force. The lens carrier includes an object-side part, a mounting structure and a plurality of plate portions. The object-side part includes a tip-end minimal aperture configured for light to travel through; and a tapered surface which surrounds an area tapered off from image side to object side. The mounting structure and the plate portions are configured for at least a part of the electromagnetic driving component assembly to be mounted thereto.

Abstract: A plastic barrel includes an inner portion and an outer portion. The inner portion defines an interior space. The inner portion includes, in order from an object side to an image side, an object-side opening, a plurality of inner annular surfaces and an image-side opening. The interior space is configured for accommodating an imaging lens assembly, and the imaging lens assembly includes a plurality of plastic lens elements. The outer portion surrounds the inner portion. The outer portion includes a mounting structure. The mounting structure is disposed on a surface of the outer portion. The mounting structure is injection molded for mounting a planar conductive element and a wiring element. The mounting structure includes at least three gate traces, and the three gate traces are located on a surface of the mounting structure.
