摘要： An imaging lens assembly includes a first plastic lens element and a second plastic lens element arranged along an optical axis. The first plastic lens element includes, in order from a paraxial region to a peripheral region, a first optically effective portion, a first size reduction portion and a first peripheral portion. An object-side surface and an image-side surface of the first size reduction portion each has a roughened surface. The first peripheral portion is to be in physical contact and assembled with adjacent components. The second plastic lens element includes, in order from a paraxial region to a peripheral region, a second optically effective portion, a second size reduction portion and a second peripheral portion. An object-side surface and an image-side surface of the second size reduction portion each has a roughened surface. The second peripheral portion is to be in physical contact and assembled with adjacent components.
