Abstract: A lens module is provided, which includes one or more first lenses arranged along an optical axis and one or more second lenses arranged along the optical axis. A radial size of the second lens is larger than that of the first lens. A circumferential surface of the second lens with a larger radial size is formed through enclosing by one or more sections of cylindrical surface and a connection surface connected to the cylindrical surface. Compared with setting the circumferential surface to a complete cylindrical surface, the connection surface is formed in a radial direction of the second lens by cutting off a part, so that a vertical distance from an optical axis of the second lens to the connection surface decreases, and an optical axis of the photographing module is closer to a side frame of a mobile terminal, thereby reducing a width of a non-display area.
