Abstract
A touch sensor having a visible area and a peripheral area includes a substrate, a metal nanowire layer, and a silver layer. The metal nanowire layer is disposed on a main surface of the substrate and defines an electrode portion and first and second wirings, in which the first wiring includes a lead-out portion connected to the electrode portion and a lead portion connected to the lead-out portion, and the second wiring is disposed on a side of the first wiring relatively away from the visible area and adjacent to an edge of the main surface. The silver layer is stacked on the first and second wirings and has a first side facing toward the visible area and a second side facing away from the visible area, and an edge roughness on the first side is greater than an edge roughness on the second side.
