  • Publication number: 20250013038
    Abstract: An imaging lens assembly module includes an imaging lens element set, a light folding element and a plate-shaped light blocking element. The imaging lens element set has an optical axis, and includes a lens element. The light folding element is configured to fold the optical axis at least once, and includes an incident surface, an exit surface and an optical reflecting surface. The plate-shaped light blocking element keeps an air distance between the plate-shaped light blocking element and the light folding element, and includes two layered structures and columnar air structures. The layered structures are corresponding to the light folding element. The columnar air structures are farther away from the light folding element than a surface of the plate-shaped light blocking element from the light folding element, and the surface of the plate-shaped light blocking element faces toward the light folding element.
