摘要： An imaging lens assembly module includes a lens barrel, a catadioptric lens assembly, an imaging lens assembly, a first fixing element and a second fixing element. The lens barrel has a first relying surface and a second relying surface, which face towards an object side of the imaging lens assembly module. The catadioptric lens assembly relies on the first relying surface. The imaging lens assembly is disposed on an image side of the catadioptric lens assembly, and relies on the second relying surface. The first fixing element is for fixing the catadioptric lens assembly to the lens barrel. The second fixing element is for fixing the imaging lens assembly to the lens barrel. The catadioptric lens assembly is for processing at least twice internal reflections of an image light in the imaging lens assembly module, and for providing optical refractive power.
