Summary:A lens barrel including a barrel wall and a sleeve. The barrel wall extends around an optical axis and from an object side to an image side. The barrel wall has a lens barrel inner surface facing the optical axis and a lens barrel outer surface facing away from the lens barrel inner surface. The lens barrel outer surface includes a lens barrel object-side surface facing the object side. The sleeve is fixed on the lens barrel outer surface and is partially embedded into the barrel wall. The sleeve has an object-side end closest to the object side and an image-side end closest to the image side. The object-side end does not extend beyond the lens barrel object-side surface that is not covered by the sleeve and closest to the object-side end in a direction parallel to the optical axis. Wherein the lens barrel object-side surface that is closest to the object-side end is closer to the object side than the image-side end.
