Abstract: An optical lens assembly is provided in the present disclosure. The optical lens assembly includes, from an object side to an image side, at least five optical lens elements. At least one of the optical lens elements includes an anti-reflective coating, and the optical lens element including the anti-reflective coating is made of a plastic material. The anti-reflective coating is arranged on an object-side surface or an image-side surface of the optical lens element including the anti-reflective coating. The anti-reflective coating includes at least one coating layer, and the coating layer at the outer of the anti-reflective coating is made of metal oxide. The anti-reflective coating includes a plurality of holes, and sizes of the holes adjacent to the outer of the anti-reflective coating are relatively larger than sizes of the holes adjacent to the inner of the anti-reflective coating.
