Abstract
An imaging lens consisting of, in order from an object side to an image side: a first lens group; a stop; and a second lens group having a positive refractive power, in which the first lens group includes three or more Ln lenses that are consecutively disposed, the Ln lens is a negative lens in which a surface on the image side is a concave surface, and in a case in which, among the three or more Ln lenses that are consecutively disposed and included in the first lens group, for two Ln lenses selected in descending order of refractive power, an average of Abbe numbers and an average of partial dispersion ratios are included within a predetermined region in a Cartesian coordinate system with a horizontal axis representing Abbe number and a vertical axis representing partial dispersion ratio.
