A method for making a nerve graft includes the following steps. A culture layer including a carbon nanotube film structure and a protein layer is provided. The protein layer is located on a surface of the carbon nanotube film structure. A number of nerve cells are seeded on a surface of the protein layer away from the carbon nanotube film structure. The nerve cells are cultured until a number of neurites branch from the nerve cells and are connected between the nerve cells.
