Abstract: An imaging lens includes a lens barrel, an imaging unit and a light shielding unit. The lens barrel includes a base wall formed with a light incident hole at an optical axis of the imaging lens and a surrounding wall that extends from and cooperates with the base wall to define a receiving space. The imaging unit includes a plurality of imaging components each having an annular front contact surface and an annular back contact surface. The light shielding unit includes an annular retaining portion clamped between an adjacent pair of the imaging components, an object-side protruding portion with a first edge, and an image-side protruding portion with a second edge.

Abstract: An imaging lens includes a lens barrel having a base wall with a light incident hole around an optical axis, an imaging unit disposed in the lens barrel and including imaging components arranged along the optical axis, and a light shielding plate having an annular fixing portion for positioning the light shielding plate and a bent portion bent from an inner periphery of the fixing portion and extending slantingly toward the optical axis. The light shielding plate is disposed at one of a position between the base wall and one of the imaging components that is adjacent to the base wall, and a position between two adjacent ones of the imaging components.
