Abstract: An imaging lens includes a first lens having a convex surface toward an object and positive refractive power, a second lens having positive or negative refractive power, a third lens having positive or negative refractive power, a fourth lens having a convex surface toward an image plane and positive refractive power, and a fifth lens having a concave surface toward an object and negative refractive power. The first through fifth lenses are arranged in order from an object to an image plane. The imaging lens satisfies the condition −0.2≦(Y−yp)/yp≦−0.05, wherein Y indicates an image height of a real chief ray, and yp indicates an image height of a paraxial chief ray.
