Abstract:
A lens module (100), comprising a lens barrel (10) with an accommodating space (101), and a lens group (20) accommodated in the accommodating space (101). The lens group (20) comprises a first lens (21) located on an object side; the first lens (21) comprises an optical portion (211) used for imaging and a bearing portion (212) arranged around the optical portion (211); the bearing portion (212) comprises a top face (213) close to the object side; and the optical portion (211) comprises an object-side face (214) close to the object side, and a side surface (215) by means of which the object-side face (214) and the top face (213) are connected to each other, the side surface (215) being coated with a light absorption layer (30). In the lens module (100), the side surface (215) is coated with the light absorption layer (30), the light absorption layer (30) can absorb most of light irradiated on the side surface (215), and stray light is effectively reduced, such that the imaging quality of the lens module (100) is improved.
