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.
