Abstract
A lens module including may include: a first lens having negative refractive power; a second lens of which an object-side surface or an image-side surface is convex; a third lens of which an image-side surface is concave; a fourth lens having refractive power; a fifth lens having refractive power; and a sixth lens having an inflection point formed on an image-side surface or an object-side surface thereof. The first to sixth lenses are disposed in a sequential order from the first lens to the sixth lens.
