Patent ID: 8000037

Claim:
An imaging lens, comprising, in order from an object side: a first lens having a positive refractive power; a second lens having a concave shape toward the object side; and (i−2) number of lens, where i is equal to or greater than 3, wherein an i-th lens, which is counted from the object side, includes: an i-th lens flat plate; and a lens element which is provided on at least one of an object-side surface and an image-side surface of the i-th lens flat plate, has a refractive index different than the i-th lens flat plate, and has a positive refracting power or a negative refracting power, wherein the following conditional relationship is satisfied: 0.9 >Y max /Y >0.61 (1) where: Y max is a distance from an optical axis to a point, which is on an image-side surface of an (i−1)th lens, which is counted from the object side, and at which a principal ray of the most outer light beam passes through; and Y is a maximum image height depending on the imaging lens and a size of an imaging device.
