1. A lens module comprising:
a first lens having positive refractive power;
a second lens having a refractive power;
a third lens having positive refractive power;
a fourth lens having negative refractive power and a concave image-side surface;
a fifth lens having a concave object-side surface;
a sixth lens having a refractive power; and
a seventh lens having a convex object-side surface,
wherein the first to seventh lenses are sequentially disposed in numerical order from an object side of the lens module,
wherein a radius of curvature of an object-side surface of the fourth lens is greater than a radius of curvature of an object-side surface of the second lens.
