Camera module

A camera module comprising:

• a lens barrel;
• and
• a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens having a negative refractive power, that are sequentially arranged in the lens barrel along an optical axis of the camera module from an object side to an image side,
• wherein the camera module further comprises a first spacer arranged between the first lens and the second lens on the optical axis, a second spacer arranged between the first lens and the second lens on the optical axis, a third spacer arranged between the third lens and the fourth lens on the optical axis, a fourth spacer arranged between the fourth lens and the fifth lens on the optical axis, a fifth spacer arranged between the fifth lens and the sixth lens on the optical axis, and a sixth spacer arranged between the sixth lens and the seventh lens on the optical axis of the camera module;
