Optical imaging lens

An optical imaging lens, comprising a plurality of lens elements, positioning from an object side to an image side along an optical axis, each of which comprises an object-side full surface facing the object side and an image-side full surface facing the image side and an optical portion and an mounting portion, formed in a radial direction, from center to edge, the object-side full surface of each of which comprises an objects-side bearing surface corresponding to the mounting portion, and the image-side full surface of each of which comprises an image-side bearing surface corresponding to the mounting portion, and between two of the lens elements, the optical imaging lens comprising:

• a light-shielding plate, comprising an object-side surface facing the object side and an image-side surface facing the image side;
• and
• two pieces of activated reactive bonding film, being in a shape of ring, one of which is positioned between the object-side surface of the light-shielding plate and the image-side bearing surface of one of the two lens elements, and the other one of which is positioned between the image-side surface of the light-shielding plate and the object-side bearing surface of the other one of the two lens elements,
• wherein with respect to each of the two pieces of activated reactive bonding film, a maximum width of the piece of activated reactive bonding film in a radial direction is represented by Wdsf, a width of one of the image-side bearing surfaces or the object-side bearing surfaces which bears the light-shielding plate in a radial direction is represented by Lms, a width of the light-shielding plate in a radial direction is represented by Ws, and the optical imaging lens satisfies two inequalities:
• 0.05 mm≤Wdsf−Lms≤Ws−Lms and 0.1 mm≤Wdsf≤0.7 mm.
