摘要

Provided is an imaging lens, including, in order from an object side: a positive first lens; a second lens having a concave shape toward the object side; and (i−2) number of lens, wherein the i-th lens, which is the most image-side lens, includes: an i-th lens flat plate; and a positive or negative lens element on at least one of the opposite surfaces of the i-th lens flat plate, wherein the following conditional relationship is satisfied: 0.9>Ymax/Y>0.61, where: Ymax is a height of the most off-axial ray on an image-side surface of the (i−1)th lens; and Y is a maximum image height.
