Abstract
An imaging lens assembly includes a plastic barrel and an optical element set. The optical element set includes an optical lens element, a light blocking sheet and a light-shielding layer. At least one surface of an object-side peripheral surface and an image-side peripheral surface of the optical lens element includes an annular side wall. An annular abutting surface of the light blocking sheet and the annular side wall of the optical lens element are disposed correspondingly to each other. The light-shielding layer surrounds a central opening of the light blocking sheet and includes an annular concave-curved portion. The annular concave-curved portion is for retaining the light blocking sheet, so that there is no relative displacement in a direction parallel to an optical axis between the annular abutting surface of the light blocking sheet and the annular side wall of the optical lens element.
