Method for manufacturing touch-panel conductive sheet, and touch-panel conductive sheet
First Claim
1. A touch-panel conductive sheet comprising:
- a substrate;
first detection electrodes which are arranged on a rear surface of the substrate;
first lead-out wires of which one ends are electrically connected to the first detection electrodes and the other ends are arranged on a front surface of the substrate, and which include through wires as a part;
second detection electrodes which are arranged on the front surface of the substrate; and
second lead-out wires which are electrically connected to the second detection electrodes,wherein the first detection electrodes, the second detection electrodes, the first lead-out wires, and the second lead-out wires contain the same metallic material,wherein the through wires are electrically connected to the first pad portions and second pad portions by through holes filled with a conductive material,wherein the through holes penetrate the first pad portions, the substrate, and the second pad portions,wherein the first pad portions are provided at end portions of the first detection electrodes or at the first lead-out wires, andwherein the second pad portions are arranged at positions opposed to the first pad portions via the substrate.

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.
