Abstract: An imaging lens is provided. The imaging lens includes, in an order from an object side to an image plane side, a first lens having an object side surface that is convex and having a positive refractive power, a second lens having a positive or negative refractive power, a third lens having a positive or negative refractive power, a fourth lens having a negative refractive power, and a fifth lens having a positive or negative refractive power, wherein an image side surface of the fifth lens has a concave center portion and has at least one inflection point, and the imaging lens satisfies a condition that −0.25≦(Y−yp)/yp≦−0.05, where Y denotes an image height of a real chief ray, and yp denotes an image height of a paraxial chief ray.
