A camera module includes a lens barrel holding a lens, and a main body holding the lens barrel, the lens barrel being capable of moving relative to the main body in the direction of the optical axis of the lens. The lens barrel has a protuberance on the underside thereof throughout the circumferential direction. The main body has a recess at a position corresponding to the protuberance of the lens barrel throughout the circumferential direction, the recess accommodating the protuberance. The protuberance is formed so as to have a height such that the protuberance is disposed in the recess both before and after the movement of the lens barrel relative to the main body in the direction of the optical axis of the lens.
