An imaging lens satisfies the following conditional expression (1) and is configured by disposing a first lens group that has a positive refractive power, an aperture stop, and a second lens group that has a positive refractive power in order from an object side to an image side. The first and second lens groups are moved from the image side to the object side in a state in which a gap between the lens groups is constant on an optical axis when a subject distance changes from infinity to approach, and the second lens group is configured by at least two negative lenses and at least three positive lenses.0.01&#x3c;2/1&#x3c;0.23&#x2003;&#x2003;(1)

Imaging lens and imaging device

There is provided An imaging lens including a first lens group having a positive refractive power, an aperture stop, and a second lens group having a positive refractive power that are configured to be arranged sequentially from an object side to an image side. Focus is achieved by fixing the first lens group in an optical axis direction and moving the second lens group from the image side to the object side when a subject distance is changed from infinity to proximity. The first lens group includes an object-side lens group having a negative refractive power and an image-side lens group having a positive refractive power that are configured to be arranged sequentially from the object side to the image side. In an air space of the first lens group, an air space between the object-side lens group and the image-side lens group is set to be maximum.
