Abstract
The imaging lens includes, successively in order from a position closest to an object side to an image side: a first lens group; and a second lens group that has a positive refractive power. During focusing, only the second lens group moves. A lens closest to the image side in the second lens group is a negative meniscus lens having a surface convex toward the object side. Assuming that a paraxial radius of curvature of an object side surface of the negative meniscus lens closest to the image side in the second lens group is rF, and a maximum image height is Y, the imaging lens satisfies Conditional Expression (1), which is represented by 0.5<rF/Y<3 (1).
