Abstract
An imaging lens includes: a first lens with a meniscus shape having a concave surface facing an object side; a second positive lens; a third negative lens with a meniscus shape having a convex surface facing an image side; and a fourth negative lens. The first to fourth lenses are arranged in this order from the object side. The imaging lens is configured such that a normal line of an object-side surface of the fourth lens at a point where the outermost light beam of an on-axis light flux passes intersects the optical axis on the image side of the object-side surface.
