Abstract
When an optical image is formed through an imaging lens on an imaging surface that is convex toward a light incident side, the imaging lens is constructed in such a manner that a defocus MTF peak position at an arbitrary image height in a range of from 70% to 100% of a maximum image height of the optical image is located further in a light-traveling direction than a same kind of defocus MTF peak position on an optical axis of the imaging lens.
