[0100] One aspect of the present disclosure provides an imaging lens module having an imaging surface (Image Surface), and comprising an optical lens, a plurality of monomer structures (Monomer Structure) and a cover member (Cover Member). The optical lens is disposed on the object side of the imaging surface and defines an optical axis. The optical lens comprises a shading element, which comprises a shading portion, and the shading portion is closer to the optical axis than the portion of the shading element other than the shading portion. The monomer structures are disposed on the object side of the imaging surface, and each monomer structure extends in a direction parallel to the optical axis. The cover member is disposed on the object side of the optical lens, and the optical axis passes through the cover member. The monomer structure is disposed on the shading portion of the shading element. The length of each monomer structure along the direction parallel to the optical axis is D, and a spacing distance between the monomer structures is Dp, which satisfies the following conditions: 0.03mm≤D<0.12mm; and 0.02mm≤Dp<0.095mm.

[0101] Furthermore, the first to fifth embodiments of the first embodiment of the present disclosure may be examples of the aforementioned imaging lens module. A plurality of monomer structures extend in a direction parallel to the optical axis, and may be presented as a convex columnar structure that grows a certain height from a setting surface of the shading portion, or a concave columnar structure that is recessed a certain depth from a setting surface of the shading portion toward another surface, but is not limited thereto. The outer cover element may be made of a transparent material such as plastic or glass, but is not limited thereto. The shading element may be a lens barrel, a fixing ring, a spacer ring, a shading sheet, etc., but is not limited thereto.

[0102] Furthermore, in a miniaturized imaging lens module, the distance between the outer cover element and the light shielding element is short, which may easily cause unnecessary optical reflections (e.g. Figure 1D and Fig.8D Thus, the present disclosure sets multiple monomer structures on a specific area of ​​the light shielding portion by means of injection molding mold transfer or laser beam processing, so as to reduce the reflectivity of light in the specific area.

[0103] One aspect of the present disclosure provides an imaging lens module having an imaging surface and including an optical lens, a light shielding element, a plurality of monomeric structures, and an outer cover element. The optical lens is disposed on the object side of the imaging surface and defines an optical axis. The light shielding element is disposed opposite to the optical lens and includes a light shielding portion, and the light shielding portion is closer to the optical axis than the portion of the light shielding element other than the light shielding portion. The monomeric structures are disposed on the object side of the imaging surface, and each monomeric structure extends along a direction parallel to the optical axis. The outer cover element is disposed on the object side of the optical lens, and the optical axis passes through the outer cover element. The monomeric structures are disposed on the light shielding portion of the light shielding element. The length of each monomeric structure along the direction parallel to the optical axis is D, and the spacing distance between the monomeric structures is Dp, which satisfy the following conditions: 0.03 mm ≤ D < 0.12 mm; and 0.02 mm ≤ Dp < 0.095 mm. Thereby, the plurality of monomeric structures can disrupt the reflection path of non-imaging light and prevent non-imaging light from entering the optical lens, thereby making the image画面 clear.

[0104] Furthermore, a second embodiment of the present disclosure may be an example of the foregoing imaging lens module. The imaging lens module may further include a variable aperture module, which is disposed on the object side of the optical lens, and the optical axis passes through the center of the variable aperture module. The variable aperture module includes at least two of the light shielding elements, and each light shielding element is stacked on each other along a circumferential direction around the optical axis to form a variable aperture, and the present disclosure is not limited thereto.

[0105] Specifically, the number of monomeric structures is Nm, which can satisfy the following conditions: 250 < Nm < 25000. Thereby, the set range of the number can enable the monomeric structures to have a better light shielding effect.

[0106] The light shielding portion may face the object side of the optical lens. Thereby, the configuration helps the light shielding portion to have a better efficiency of intercepting non-imaging light.

[0107] The light shielding element may extend along the direction parallel to the optical axis. The light shielding element may further include an object side surface, which is located at the most object side portion of the light shielding element. The object side surface may face the object side of the optical lens.

[0108] The height difference along the direction parallel to the optical axis between the object side surface and the setting surface of the monomeric structure is ΔH, and the length of the light shielding element along the direction parallel to the optical axis is Lb, which can satisfy the following conditions: 0 ≤ ΔH / Lb < 0.8. Thereby, the continuity of the coverage range of the monomeric structures can be ensured to maintain a high light shielding effect.

[0109] The monomeric structures may face the object side of the optical lens. Thereby, the configuration helps the monomeric structures to have a better light shielding effect.

[0110] The outer cover element may correspond to and face the light shielding portion of the light shielding element. Thereby, the configuration helps the light shielding portion to have a better efficiency of intercepting non-imaging light.

[0111] The light-shielding element may be composed of at least two structural layers. Specifically, the light-shielding element may be a light-shielding sheet, but is not limited thereto. The at least two structural layers may include a base layer and a covering layer.

[0112] The thickness of the base layer is Ts, and the thickness of the covering layer is Tc, which may satisfy the following condition: 0.03 mm ≤ D < Ts + Tc < 0.5 mm. Thereby, this range is a preferable thickness setting range that takes into account both the light-shielding effect of the monomer structure and the production efficiency of the light-shielding element.

[0113] Each technical feature in the imaging lens module of the above disclosure can be combined and configured to achieve the corresponding effects.

[0114] One aspect of the disclosure provides a camera module including the aforementioned imaging lens module.

[0115] One aspect of the disclosure provides an electronic device including the aforementioned camera module.
