An imaging lens consisting essentially of six lenses, composed of, in order from the object side, a first lens having a positive refractive power with a convex surface on the object side, a second lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, a fifth lens having a negative refractive power with a concave surface on the image side, and a sixth lens having a negative refractive power, in which predetermined conditional expressions are satisfied.
