The invention discloses a capacitive touch screen and a manufacturing method thereof. A bridging jumper wire comprises two groups of line conductor transparent conductive films, an insulating film and a metallic bridging film layer which are arranged on a base plate; the first group of line conductor transparent conductive films are arranged continuously, and the second group of line conductor transparent conductive films are arranged sectionally by taking the first group of line conductor transparent conductive films as spacers; the insulating film covers the first group of line conductor transparent conductive films and the adjacent base plate surface at the intersection of two groups of line conductors; the metallic bridging film crosses over the insulating film to connect the second group of line conductor transparent conductive films arranged at intervals as a continuous body and covers the surface of the base plate. The method comprises the steps of: manufacturing two groups of line conductor conductive files, and manufacturing the insulating film and manufacturing the metallic bridging film. In the invention, the transparent conductive films of two groups of line conductors can be manufactured at the same time, thereby avoiding chromatic aberration and improving the quality of the touch screen; the margin of the insulating film is located on the base plate, and the metallic bridging film layer can not be broken, thereby improving the yield of the product; the metallic bridging film layer is thick and not easy to be broken; and the metallic bridging film layer has small wire resistance, thereby improving the performance of the touch screen.
