An imaging lens is constituted essentially by six lenses, including, in order from the object side to the image side: a first lens having a positive refractive power and a convex surface toward the object side; a second lens having a negative refractive power; a third lens having a positive refractive power and is of a biconvex shape; a fourth lens having a positive refractive power; a fifth lens having a negative refractive power and a concave surface toward the object side; and a sixth lens having a negative refractive power, of which the surface toward the image side is of an aspherical shape which is concave in the vicinity of the optical axis and convex at the peripheral portion thereof. Predetermined conditional formulae are satisfied.
