Claim 12:
13. A lens module comprising:
a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens each having a respective refractive power 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,
wherein the third lens has a concave object-side surface in an optical axis portion thereof and a concave image-side surface in an optical axis portion thereof,
a sign of the refractive power of the first lens is the same as a sign of the refractive power of the fifth lens,
a sign of the refractive power of the second lens is the same as a sign of the refractive power of the fourth lens,
the fourth lens has a focal length in a range of 2.0 mm to 2.40 mm, 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.
