The present disclosure relates to a method for making a plurality of touch panels one time. The method includes following steps. A substrate is provided. The substrate has a surface defining a number of target areas with each including two areas: a touch-view area and a trace area. An adhesive layer is formed on the surface of the substrate. A carbon nanotube film is formed on the adhesive layer. The adhesive layer is solidified. An electrode and a conductive trace are formed on each target area so that part of the carbon nanotube film is exposed from a space between adjacent conductive lines of the conductive trace to form an exposed carbon nanotube film on each trace area. The exposed carbon nanotube film on each trace area is removed to obtain a plurality of transparent conductive layers spaced from each other. A number of touch panels is obtained by cutting the substrate.
