A method for making a strip shaped graphene layer includes the steps of: first, a graphene film is located on a surface of a substrate is provided. Second, a drawn carbon nanotube film composite is disposed on the graphene film. The drawn carbon nanotube film composite includes a polymer material and a drawn carbon nanotube film structure disposed in the polymer material. The drawn carbon nanotube film structure includes a plurality of carbon nanotube segments and a plurality of strip-shaped gaps between the adjacent carbon nanotube segments. Third, the polymer material is partly removed to expose the plurality of carbon nanotube segments. Forth, the plurality of carbon nanotube segments and the graphene film covered by the plurality of carbon nanotube segments is etched. Fifth, the remained polymer material is removed to obtain the strip shaped graphene layer.
