An imaging lens is constituted by, in order from the object side to the image side: a first lens having a negative refractive power and a concave surface toward the image side; a second lens having a negative refractive power; a third lens having a positive refractive power and a convex surface toward the image side; a fourth lens having a negative refractive power and a concave surface toward the image side; a biconvex fifth lens which is cemented to the fourth lens; and a sixth lens having a negative refractive power and a concave surface toward the object side.
