A compact imaging lens includes, in order from an object side: a first lens group having positive refractive power and consisting of a single lens element; and a second lens group having positive refractive power and consisting of a plurality of lens components. A position of the first lens group is fixed with respect to an image plane. At least a portion of the second lens group is moved as a shift lens group in a direction including a component perpendicular to an optical axis. Specified conditional expressions are satisfied.
