Claim 0:
1. A lens module comprising:
a first lens having a convex object-side surface in an optical axis portion thereof;
a second lens having a convex object-side surface in an optical axis portion thereof and a convex image-side surface in an optical axis portion thereof;
a third lens having a concave object-side surface in an optical axis portion thereof and a concave image-side surface in an optical axis portion thereof;
a fourth lens having a positive refractive power, a convex object-side surface in an optical axis portion thereof, a convex image-side surface in an optical axis portion thereof, and a focal length in a range of 2.0 mm to 2.40 mm;
a fifth lens having a concave object-side surface in an optical axis portion thereof; and
a sixth lens having a convex object-side surface in an optical axis portion thereof and an image-side-surface having one or more inflection points thereon,
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 the 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.
