METHOD FOR MANUFACTURING TOUCH-PANEL CONDUCTIVE SHEET, AND TOUCH-PANEL CONDUCTIVE SHEET

摘要

An object of the invention is to provide a method for more easily manufacturing a touch-panel conductive sheet in which end portions of lead-out wires are collected on one surface side of a substrate with high productivity, and a touch-panel conductive sheet. The method for manufacturing a touch-panel conductive sheet of the invention includes: forming, on a rear surface of a substrate, first detection electrodes and rear surface-side wires of which one ends are electrically connected to the first detection electrodes and the other ends have first pad portions, and on a front surface of the substrate, second detection electrodes, second lead-out wires which are electrically connected to the second detection electrodes, and second pad portions which are arranged at positions opposed to the first pad portions via the substrate; forming through holes penetrating the first pad portions, the substrate, and the second pad portions; and producing through wires which electrically connect the first pad portions and the second pad portions by filling the through holes with a conductive material to form first lead-out wires which include the rear surface-side wires and the through wires and are electrically connected to the first detection electrodes.
