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.
