An imaging lens substantially consisting of a first lens group, a stop, and a second lens group in this order from the object side, the first lens group includes at least a positive lens, a negative meniscus lens with a convex surface toward the object side, a biconcave negative lens, and a cemented lens substantially constituted by two lenses, which are a positive lens and a negative lens, in this order from the object side; the second lens group includes at least a first positive lens with a convex surface toward the image side, a cemented lens substantially constituted by two lenses, which are a positive lens and a negative lens, and a second positive lens with a convex surface toward the image side, in this order from the object side; and a predetermined conditional expression is satisfied.
