Kind Code:

Abstract:
Disclosed are a camera module (10) and an electric device (1), the camera module (10) comprising a lens set (200) and a lens barrel (100), wherein the lens set (200) comprises a plurality of lenses that are sequentially arranged from the object side to the image side; and the lens barrel (100) comprises an accommodating cavity (150) allowing the lens set (200) to be mounted, and an inner side wall (110) corresponding to the accommodating cavity (150) and close to the image side, with the inner side wall (110) being provided with a plurality of first light extinction grooves (111) that are arranged in an array, and with each of the first light extinction grooves (111) being arranged in an extending manner in the axial direction of the lens barrel (100). The inner side wall (110), close to the image side, of the accommodating cavity (150) of the lens barrel (100) is provided with the plurality of first light extinction grooves (111) that are arranged in an array, such that after light rays are emitted into the first light extinction grooves (111) that are arranged in an array, the light rays can be reflected multiple times to achieve a scattering effect, thereby reducing the formation of stray light that interferes with imaging of the camera module (10), and thus improving the imaging quality of the camera module (10).
