Abstract
An imaging lens substantially consists of a first-lens-group, a stop and a second-lens-group in this order from object-side. The first-lens-group has a 1-1st-lens having negative-refractive-power and a meniscus-shape with its convex-surface facing object-side and a 1-2nd-lens having positive-refractive-power, and an object-side-lens-surface of which has a convex-shape facing object-side. The second-lens-group has a 2-1st-lens having positive-refractive-power and a meniscus-shape with its convex-surface facing image-side, a 2-2nd-lens having negative-refractive-power, and an object-side-lens-surface of which has a concave-shape facing object-side, and the absolute-value of a curvature-radius of the object-side-lens-surface is less than the absolute-value of a curvature-radius of an image-side-lens-surface thereof, and a 2-3rd-lens having positive-refractive-power, and an object-side-lens-surface of which has a convex-shape facing object-side, in this order from object-side.
