1. A lens module comprising:
a first lens having a positive refractive power, an image-side surface of the first lens being concave;
a second lens having a negative refractive power;
a third lens having a positive refractive power;
a fourth lens having a refractive power;
a fifth lens having a refractive power;
a sixth lens having a refractive power; and
a seventh lens having a negative refractive power, an image-side surface of the seventh lens having one or more inflection points,
wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, and the seventh lens are disposed in a sequential order from the first lens to the seventh lens,
an object-side surface of the fourth lens is concave,
an object-side surface of the fifth lens is concave,
an image-side surface of the sixth lens is concave, or an object-side surface of the seventh lens is convex, or both an image-side surface of the sixth lens is concave and an object-side surface of the seventh lens is convex,
an image-side surface of the fourth lens is convex, and
an object-side surface of the third lens is convex.
