Claim 37:
38. An imaging lens assembly, having an optical axis, comprising:
a plurality of optical elements, the optical axis passing through the optical elements; and
an accommodating assembly surrounding the optical axis and containing the optical elements, the accommodating assembly comprising:
a conical-shaped light blocking sheet having an opening, the optical axis passing through the opening, the conical-shaped light blocking sheet comprising:
an out-side portion defining an outer periphery of the conical-shaped light blocking sheet and surrounding the opening; and
a conical portion forming the opening and connecting to the out-side portion, wherein the conical portion comprises a conical structure tapered from the out-side portion toward one of an object-side and an image-side along the optical axis; and

a lens barrel disposed on one of an object side and an image side of the conical portion, comprising:
an object-side wall having an object-side through hole and facing towards an object side of the imaging lens assembly;
an image-side wall having an image-side through hole and facing towards an image side of the imaging lens assembly;
an inner-side wall surrounding and facing towards the optical axis, the inner-side wall connecting the object-side wall and the image-side wall; and
an outer-side wall farther away from the optical axis than the inner-side wall to the optical axis and connecting the object-side wall and the image-side wall;

wherein the optical elements comprise a most object-side optical element, a most image-side optical element and at least one optical element;
wherein the conical structure of the conical-shaped light blocking sheet is physically contacted with only one of the lens barrel, an object side of the most object-side optical element and an image side of the most image-side optical element.
