A lens barrel includes a front end portion. The front end portion includes an outer surface facing toward an object side and an inner surface facing toward an image side. The inner surface includes an inner side conical surface. The inner side conical surface is connected to the outer surface. The inner-side conical surface includes a plurality of toothed structures, an inner edge near an optical axis and an outer edge away from the optical axis. The outer edge is closer to the image side than the inner edge. The inner edge forms a clear hole. Each of the toothed structures includes a tooth peak and a tooth valley. The tooth peak and the tooth valley are disposed at the inner edge, and the tooth peak extends from the inner edge to the outer edge to form a convex strip.
