The invention relates to a method for manufacturing a touch screen comprising the following steps: providing a carbon nano tube array formed on a substrate and a first matrix and a second matrix; obtaining a carbon nano tube layer separately formed on the surfaces of the first matrix and the second matrix by extruding the carbon nano tube array, forming a first conductive layer and a second conductive layer, further forming a first electrode board and a second electrode board; arranging two first electrodes on the first electrode board, arranging two second electrodes on the second electrode board, and spacedly arranging the first electrode board and the second electrode board, and obtaining the touch screen by oppositely arranging the first conductive layer and the second conductive layer.
