Claim 10:
11. A lens module comprising:
a first lens having a negative refractive power;
a second lens having a positive refractive power;
a third lens having a negative refractive power;
a fourth lens having a positive refractive power and a focal length in a range of 2.0 mm to 2.40 mm;
a fifth lens having a negative refractive power; and
a sixth lens having a refractive power and an image-side surface having one or more inflection points,
wherein the first to sixth lenses are sequentially disposed in ascending numerical order along an optical axis of the lens module from an object side of the lens module toward an image plane of the lens module, and
(r9+r10)/(r9−r10)<−6.0 is satisfied, where r9 is a radius of curvature of an object-side surface of the fifth lens on the optical axis, and r10 is a radius of curvature of an image-side surface of the fifth lens on the optical axis.
