Abstract
The imaging lens consists of, in order from an object side, a first lens group, a stop, and a positive second lens group. The second lens group has a negative lens on a side closest to an object and has a single lens or a cemented lens having a positive refractive power on a side closest to an image. Predetermined conditional expressions relating to a back focus, an incidence angle of a principal light ray on the image plane, a maximum image height, a distance from a lens surface on the side closest to the object to a lens surface on the side closest to the image, a distance from an object side principal point of the second lens group to a stop, and a focal length of the second lens group are satisfied.
