Imaging lens assembly, imaging apparatus and electronic device

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 image-side opening, the optical axis passing through the image-side 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 image-side opening;
• and
• a conical portion forming the image-side opening and connected to the out-side portion, wherein the conical portion comprises a conical structure tapered from the out-side portion toward an image-side along the optical axis;
• and
• a lens barrel disposed on an object 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 accommodating assembly defines an inner space extending from the object-side through hole of the lens barrel to an end of the conical portion closest to the image side along a direction parallel to the optical axis and surrounded by the inner-side wall;
• wherein the optical elements comprise a most image-side optical element and at least two optical elements disposed in the inner space;
• wherein the out-side portion is fixed at only one of the lens barrel and the most image-side optical element, and the conical-shaped light blocking sheet is physically contacted with only one of the lens barrel and the most image-side optical element.
