Abstract
A lens module includes a lens barrel, a lens and an aperture plate. The lens barrel includes a main body. The lens barrel includes a main body with an inner sidewall. The lens is received in the main body and includes an optical portion and a non-optical portion surrounded the optical portion. The aperture plate is disposed on the image-side surface of the non-optical portion of lens. The aperture plate defines a plurality of cutouts on the outer periphery thereof and thereby leaving a plurality of flanges at the outer periphery thereof. The flanges abut the inner side wall. The cutouts are coated adhesive to firmly attach the aperture plate on the image-side surface of the lens and fixed on the inner sidewall of the main body.
