Summary:A lens module includes a first lens having negative refractive power; a second lens having positive refractive power; a third lens having refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power. The first to fifth lenses are sequentially disposed in numerical order from an object side of the lens module toward an image plane of the lens module, and 0.3<(r1−r2)/(r1+r2) is satisfied, where r1 is a radius of curvature of an object-side surface of the first lens, and r2 is a radius of curvature of an image-side surface of the first lens.
