A touch panel and a manufacturing method thereof are provided. The touch panel includes a substrate, peripheral leads, a touch-sensing electrode, and first covers. The peripheral leads are disposed on the substrate. Each peripheral lead has a sidewall and an upper surface. The first covers cover the upper surfaces of the peripheral leads. The touch-sensing electrode includes a plurality of modified metal nanowires. The modified metal nanowires have first surfaces in direct contact with each other at an intersection. The modified metal nanowires have second surfaces with a covering structure, and the second surfaces are at non-intersections.
