Imaging lens assembly module, camera module and electronic device

An imaging lens assembly module, which has an optical axis, comprising:

• a transparent flat plate;
• a lens barrel disposed on an image side of the transparent flat plate, and comprising:
• an object-side portion surrounding the optical axis, and comprising a first assembling surface, the first assembling surface facing toward an image side of the lens barrel;
• a tubular portion surrounding the optical axis, the tubular portion connected to the object-side portion and extending to the image side of the lens barrel, and comprising a plurality of second assembling surfaces, wherein all of the second assembling surfaces face toward the optical axis, the second assembling surfaces are arranged from an object side of the lens barrel to the image side of the lens barrel in order of increasing a distance from the optical axis, and have different diameters;
• and
• a tip-end minimal aperture being a symmetrical circle about the optical axis as a center, and the tip-end minimal aperture located on the object-side portion;
• and
• an optical element set disposed in the lens barrel, comprising:
• a plurality of light blocking elements, each of the light blocking elements having an opening surrounding the optical axis, the light blocking elements comprising at least one light blocking sheet, and the at least one light blocking sheet comprising:
• an object-side surface disposed on the first assembling surface;
• an image-side surface;
• and
• an inner opening surface connected to the object-side surface and the image-side surface, and corresponding to the tip-end minimal aperture;
• and
• at least one optical lens element, in order of increasing a distance from the optical axis to a peripheral region of the at least one optical lens element, comprising:
• an optical effective portion;
• and
• a peripheral portion surrounding the optical effective portion, and disposed on one of the second assembling surfaces;
• and
• an aperture element comprising an aperture opening surrounding the optical axis, and the aperture element disposed between the transparent flat plate and the first assembling surface;
• wherein the aperture opening of the aperture element is an aperture stop of the imaging lens assembly module;
• wherein an axial distance between the aperture stop and the first assembling surface is Ds, an opening diameter of the tip-end minimal aperture is φBmin, a diameter of one of the second assembling surfaces closest to the object side of the lens barrel is φd, and the following conditions are satisfied:
• 0.25 mm<Ds<1.4 mm;
• and
• 0.6<φBmin/φd<1.0.
