    Abstract: An imaging lens element assembly includes a dual molded lens element. The dual molded lens element includes a transparent portion, a light absorbing portion and a step structure. The transparent portion, in order from a center to a peripheral region, includes an optical effective area and a transparent peripheral area, wherein an optical axis of the imaging lens element assembly passes through the optical effective area, and the transparent peripheral area surrounds the optical effective area. The light absorbing portion surrounds the optical effective area and is disposed on an object side of the transparent peripheral area and includes an object-end surface and an outer inclined surface. The object-end surface faces towards an object side of the light absorbing portion, and the outer inclined surface extends from the object-end surface to an image side of the light absorbing portion and is gradually far away from the optical axis.

    Abstract: A plastic barrel, which surrounds a central axis, includes an object-side portion and a tubular portion. The object-side portion includes an object-side opening and a reverse inclined structure. The reverse inclined structure surrounds the object-side opening and includes a reverse inclined surface and at least one annular concave structure. The at least one annular concave structure is disposed on an object side of the reverse inclined surface and recessed from the object-side opening along a direction away from the central axis, wherein a sectional surface of the at least one annular concave structure passing through the central axis includes a valley point and two concave ends, and the two concave ends are disposed on an object side and an image side of the valley point, respectively. The tubular portion is connected to the object-side portion and extends to the image side.
