Abstract: An optical lens module includes an adjustable aperture assembly including rotatable blades, a driving part and an attractive force mechanism. The rotatable blades surround an optical axis of a lens element and form a light pass aperture. The driving part includes a rotatable component, a fixed component, a driving magnet and a coil. The rotatable component rotates the rotatable blades for adjusting an aperture size of the light pass aperture. The driving magnet is disposed on the rotatable component. The coil corresponds to the driving magnet to rotate the rotatable component. The attractive force mechanism provides an attractive force between the rotatable component and the fixed component and provides a driving force exerted on the rotatable blades for maintaining the light pass aperture in an enlarged state. The attractive force includes a magnetic force exerted by the rotatable component on a first magnetic element fixed on the fixed component.

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 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.
