A surface closest to the image side in the first lens group is a second aspheric surface, whose radius of curvature is r. The second lens group is disposed between the first lens group and the image side, wherein a surface closest to the first lens group in the second lens group is a third aspheric surface, whose radius of curvature thereof is r. A surface closest to the image side in the second lens group is a fourth aspheric surface. The micro-lens module satisfies: 0.6>r>0.4 mm, and 0.3<r/r<0.6.
