Abstract

An imaging lens assembly includes a plurality of optical lens elements, a single-piece-formed light blocking sheet and a lens barrel. The lens barrel has a circular light-passing hole corresponding to the plurality of optical lens elements and the single-piece-formed light blocking sheet. The single-piece-formed light blocking sheet has a central aperture corresponding to the lens barrel and the plurality of optical lens elements. A maximum aperture diameter is defined by the central aperture. The single-piece-formed light blocking sheet comprises a plurality of light blocking structures surrounding and disposed adjacent to the central aperture. A minimum inner radius of the central aperture is defined near the center of each of the light blocking structures.
