The utility model discloses a buffer device and a camera module, relates to the technical field of cameras, and solves the technical problem that the camera module is damaged due to falling. The buffer device comprises a first magnetic part and a second magnetic part, the first magnetic part is connected with the lens, the second magnetic part is connected with the base, and magnetic poles, with the same magnetism, of the first magnetic part and the second magnetic part are oppositely arranged. According to the utility model, the first magnetic piece is added on the lens, the second magnetic piece is added on the base, and the first magnetic piece and the second magnetic piece are oppositely arranged. When the camera module falls off, the first magnetic part and the second magnetic part prevent the lens and the base from moving in opposite directions by using the principle that homopolar magnetism repels each other, and play a role in buffering collision between the lens and the base, so that the problems tha
