Optical lens assembly and optical module

An imaging lens assembly includes a first lens element, a second lens element and a lens barrel, and an optical axis passes through the imaging lens assembly. One of the space adjusting structures is formed via a first peripheral portion of the first lens element and a plate portion of the lens barrel, the other one of the space adjusting structures is formed via the first peripheral portion of the first lens element and a second peripheral portion of the second lens element. Each of the space adjusting structures includes a frustum surface, a spatial frustum surface, a corresponding structure and a spatial layer. Each of the frustum surfaces and each of the spatial frustum surfaces are disposed on an object-side surface of the first peripheral portion and an object-side surface of the second peripheral portion, respectively.

Imaging lens assembly and electronic device

An optical lens assembly includes a lens barrel and an optical lens group. The lens barrel includes a light entering hole, which is configured for allowing a light to enter the lens barrel. The lens barrel accommodates the optical lens group, and an optical axis passes through the optical lens group. The optical lens group includes a plurality of lens elements and at least one light blocking sheet. The light blocking sheet is an opaque sheet-shaped element and surrounds the optical axis to form a light passing hole. The light blocking sheet includes an object-side surface and an image-side surface, and the object-side surface is located more adjacent to the light entering hole than the image-side surface thereto. A first film layer is disposed on the object-side surface.
