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.

Touch sensor and manufacturing method thereof

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 a plurality of electrode portions corresponding to the visible area and a plurality of wiring portions corresponding to the peripheral area. The electrode portions are arranged at intervals, and the wiring portions are respectively connected to the electrode portions and arranged at intervals. Two adjacent electrode portions are spaced apart by a first spacer region, and two adjacent wiring portions are spaced apart by a second spacer region. The silver layer is disposed on the wiring portions and in contact with the wiring portions. A thickness of the substrate corresponding to the first spacer region is smaller than a thickness of the substrate corresponding to the second spacer region.
