An imaging lens includes: a movable lens group configured to travel to allow the imaging lens to come into focus; and a rearmost lens group arranged at a most-image-sided fixed position, and having negative refractive power. Following conditional expression is satisfied, -2<ft/fr<-0.45(1) where ft is a total focal length of the imaging lens in a condition that the imaging lens is in focus on an object at infinite, and fr is a focal length of the rearmost lens group. |
