Abstract
An antenna has a visible light transparent substrate, and a pattern including metal fine wires provided on the visible light transparent substrate and having a plurality of opening portions. In the pattern, a line width of the metal fine wire is 0.5 to 5.0 μm, an opening ratio is 70% or greater, and surface electrical resistance is 9 Ω/sq. or less. A method of manufacturing an antenna has a step of forming a pattern in which a line width of metal fine wires is 0.5 to 5.0 μm, and an opening ratio is 70% or greater by an electroless copper plating treatment. A touch sensor has a touch sensor unit which is provided in a visible light transparent substrate and which includes at least a detection electrode in which a plurality of opening portions are formed of conductive fine wires, and at least one antenna provided on the substrate.
