Abstract
A touch panel includes a substrate, a catalytic layer, peripheral traces, marks, first cover layers and second cover layers. The catalytic layer is formed on the peripheral area of the substrate, and the peripheral traces are formed on the catalytic layer. Each peripheral trace has a side wall and a top surface. The marks are formed on the catalytic layer, and each mark has a side wall and a top surface. The first cover layers cover the top surfaces of the peripheral traces, and the second cover layers cover the top surfaces of the marks. Each of the first cover layers and the second cover layers includes metal nanowires. The manufacturing method of the touch panel and a roll sheet of touch sensors are also disclosed.
