Abstract: 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.

Abstract: An electroconductive sheet and a touch panel having a first electroconductive section and a second electroconductive section, the second electroconductive section being disposed on the display-panel side. The first electroconductive section has a plurality of first electroconductive patterns arranged in the x-direction, a plurality of first large grids being respectively connected to the first electroconductive patterns. The second electroconductive section has a plurality of second electroconductive patterns arranged in the y-direction, a plurality of second large grids being respectively connected to the second electroconductive patterns. The area occupied by thin metal wires in the second electroconductive patterns is larger than the area occupied by thin metal wires in the first electroconductive patterns. The area occupied by thin metal wires in the second large grids is larger than the area occupied by thin metal wires in the first large grids.
