Abstract
The imaging lens consists of, in order from the object side, a first lens group having a positive refractive power, a stop, a second lens group having a positive refractive power, and a third lens group. The third lens group includes one or more positive lenses and one or more negative lenses. During focusing, an entirety of the first lens group, the stop, and the second lens group, or an entirety of the second lens group integrally moves as a focus group, and the third lens group remains stationary with respect to an image plane. The imaging lens satisfies predetermined conditional expressions.
