1. A lens module comprising:
a first lens having a refractive power;
a second lens having a refractive power;
a third lens having a concave object-side surface;
a fourth lens having a refractive power; and
a fifth lens having negative refractive power and a concave image-side surface,
wherein the first to fifth lenses are sequentially arranged in ascending numerical order from an object side of the lens module toward an image side of the lens module, and
wherein 1.0<|(1/f1+1/f2)/(1/f3+1/f4+1/f5)|<4.0, where f1 is a focal length of the first lens, f2 is a focal length of the second lens, f3 is a focal length of the third lens, f4 is a focal length of the fourth lens, and f5 is a focal length of the fifth lens.
