The imaging lens consists of, in order from the object side, a positive first lens group, a stop, a positive second lens group, and a negative third lens group. Lenses arranged first and second from the object side are both negative single lenses having convex surfaces toward the object side. The second lens group includes a cemented lens in which a negative lens and a positive lens are cemented. During focusing, only the second lens group moves. Assuming that focal lengths of the first lens group and the second lens group are f1 and f2, respectively, the imaging lens satisfies 0.7
