It can be seen that the concentricity of the lens 32 and the lens barrel 20 in the camera module 100 of the utility model is better. Even if it is affected by falling during use, the deviation between the lens 32 and the lens barrel 20 is small, and the assembly dimension chain of the lens 32 to the lens barrel 20 is small, which can give full play to the optical performance of the lens module 30, further improve the photo-taking and video-taking effects of the camera module 100, and bring people a better visual experience.

[0018] In the present invention, one or more first positioning holes 21 may be provided according to installation requirements.
