The invention relates to an imaging lens and an imaging device. The imaging lens is constituted of, in order from an object side to an image side, a first lens element having a positive refractive power and having a convex surface toward the object side; a second lens element of a meniscus shape having a negative refractive power and having a concave surface toward an image side; a third lens element having a positive refractive power and having a convex surface toward the image side; a fourth lens element of a meniscus shape having a negative refractive power and having a convex surface toward the image side; and a fifth lens element of a meniscus shape and having a concave surface toward the image side.
