Abstract: The imaging lens consists of, in order from the object side, a first lens group that has a positive refractive power, a stop, a second lens group that has a positive refractive power, and a third lens group that has a negative refractive power. During focusing, the first lens group and the third lens group remain stationary with respect to the image plane, and the second lens group moves along the optical axis. The imaging lens satisfies predetermined conditional expressions.
