An imaging lens assembly module has an optical axis, and includes a lens barrel and an optical element set. The lens barrel includes an object-side portion, a tubular portion and a tip-end minimal aperture. The object-side portion includes a first assembling surface. The tubular portion includes a plurality of second assembling surfaces. The optical element set includes at least one light blocking sheet and at least one optical lens element. The light blocking sheet includes an object-side surface, an image-side surface and an inner opening surface. The optical lens element includes an optical effective portion and a peripheral portion. The object-side portion of the lens barrel includes a first reversing inclined surface gradually enlarged from the tip-end minimal aperture to the image side of the lens barrel, and the first reversing inclined surface is not contacted with the optical element set.
