A method for making a carbon nanotube film is provided. In the method, a carbon nanotube array is grown on a substrate, and a rigid drawing device is provided. The carbon nanotube array is adhered to the rigid drawing device via an planar adhesive region of the rigid drawing device. The rigid drawing device is pulled at a speed along a direction away from the substrate, thereby pulling out a continuous carbon nanotube film. The carbon nanotube array includes a plurality of carbon nanotubes. The planar adhesive region have a linear border, wherein the linear border of the planar adhesive region is the closest border of the planar adhesive region to a surface of the substrate. The carbon nanotubes in the carbon nanotube array are adhered via the planar adhesive region.
