Complete Description of the Invention The present disclosure provides an imaging lens assembly including a plurality of optical lens elements, a one-piece molded light-blocking sheet and a lens barrel. The one-piece molded light-blocking sheet corresponds to the optical lens elements. The lens barrel has a circular light-passing hole corresponding to the optical lens elements and the one-piece molded light-blocking sheet. The one-piece molded light-blocking sheet has a central aperture corresponding to the lens barrel and the optical lens elements, and a maximum aperture diameter formed by the central aperture. The one-piece molded light-blocking sheet includes a plurality of light-blocking structures surrounding and positioned adjacent to the central aperture, and a number of the plurality of light-blocking structures is three to ten.A center of each light barrier structure is closer to a center of the central aperture than the two ends of each light barrier structure, and the two ends of each light barrier structure extend toward the maximum aperture diameter of the central aperture. When a maximum aperture radius of the central aperture is Rmax, a minimum inner radius of the central aperture is formed near the center of each light barrier structure, the minimum inner radius is Rmin, and a roundness coefficient of the central aperture is tc, the following conditions are satisfied: 0.41% < tc < 10.2%, where tc = ((Rmax-Rmin) / Rmax)*100%. Since the one-piece-molded light barrier sheet can be an aperture stop of the imaging lens assembly, the maximum aperture diameter of the central aperture is equal to an entrance pupil diameter (EPD) of the imaging lens assembly.The one-piece-molded light barrier sheet can have effects similar to the multi-blade aperture stop of a single-lens reflex camera, so that the imaging performance of the physical light source can be effectively controlled by the light barrier structures so as to make the light source identifiable, and the size of the central aperture can be precisely controlled to achieve an ideal imaging effect. It should be noted that the roundness coefficient referred to in the present disclosure is not a roundness, and the roundness can be determined as t, where t = (Rmax-Rmin). The one-piece-molded light barrier sheet may further include a plurality of radius structures, and the plurality of radius structures surround and are disposed adjacent to the central aperture. A plurality of the radius structures may be as many as three to ten, each of the radius structures being connected to two adjacent light barrier structures, and each of the radius structures may be arc-shaped. Therefore, the arc-shaped arrangement may prevent excessive light blocking and affect the specifications of the imaging lens assembly. When a curvature radius of each radius structure is R, the following conditions are met: 0.25 mm < R < 4.2 mm. By controlling the radius structures to maintain a certain quantity, more imaging light with a higher field of view can pass through them. When the maximum aperture radius of the central aperture is Rmax, and a curvature radius of each radius structure is R, the following condition is satisfied: R = Rmax. Therefore, the higher f-number of the imaging lens assembly can be maintained assuming the identifiability of the light source is maintained. A number of radius structures and a number of light-blocking structures are placed alternately and surround the central aperture. Therefore, with the arrangement that the central aperture includes the radius structures, it is preferred to prevent excessive length of the light-blocking structures. When a focal length of the imaging lens assembly is f, and the maximum aperture radius of the central aperture is Rmax, the following conditions are met: 0.9 < F < 3.25, where F = f / 2Rmax. Therefore, within the ideal range of the sphericity coefficient, it is desirable to collect sufficient amount of imaging light so as to maintain the imaging criteria at a high level. Each of the light barrier structures is a straight-line segment, and each of the radius structures is arc-shaped. Therefore, the concentrated light beam from the strong light source will be reflected by the straight-line light barrier structures at the same time, and the arrangement of the arc-shaped radius structures can prevent the excessive light from the strong light source from being blocked by the straight-line segment, so that the imaging light from the strong light source can completely pass through. When the roundness coefficient of the central aperture is tc, the following conditions are met: 0.83% < tc < 8.6%. Therefore, it is preferred to prevent excessive light blocking, so that low-light photography will not be affected. Furthermore, the following conditions can be met: 0.83% < tc < 6.8%. Therefore, it is preferred to prevent the imaging light from being affected by weak light sources, and has better performance when shooting objects with weak light sources. Furthermore, the following conditions can be met: 0.68% d tc < 4.1%. Therefore, the amount of incoming light can be increased to ensure better imaging performance for shooting in night environments. The number of light-blocking structures can be as many as five to nine. Therefore, an appropriate number of light-blocking structures is conducive to maintaining a balance between a high amount of incoming light and high quality. When a thickness of a one-piece-molded light barrier sheet is S, the following condition is satisfied: 5 μm < S < 210 μη. Therefore, within the specific thickness range, it is not easy to generate additional non-ideal light under the conditions of strict real-life situations. The present disclosure provides an electronic device. The electronic device includes an imaging lens assembly according to the above-mentioned aspects and an image sensor disposed on an imaging surface of the imaging lens assembly.
