Abstract
The imaging lens consists of, in order from an object side, a positive first lens group, a positive second lens group, and a negative third lens group. During focusing, only the second lens group moves. The number of lenses included in the second lens group is two or less. The lens on the most object side is a negative lens having a convex surface toward the object side. The lens surface on the most image side is a convex surface. The first lens group includes a stop. Predetermined conditional expressions related to the first lens group and the second lens group are satisfied.
