Patent number: 10901563Abstract: A touch panel sensor includes a substrate and an electrode having a detection electrode and an extraction electrode connected to a detection electrode. The electrode, in any cross-section thereof in the thickness direction, includes a metal layer which occupies at least part of the cross-section. The metal layer of the detection electrode and the metal layer of the extraction electrode are formed integrally at a joint between the detection electrode and the extraction electrode. The detection electrode includes a conductive mesh having conductive wire arranged in a mesh pattern, the conductive wire having a height of not less than 0.2 ?m and not more than 2 ?m and a width of not less than 1 ?m and not more than 5 ?m. The conductive wire of the conductive mesh each have a base surface on the substrate side, and a flat top surface located opposite to the base surface.Type: GrantFiled: December 5, 2019Date of Patent: January 26, 2021Assignee: Dai Nippon Printing Co., LtdInventors: Yasuhiko Ishii, Yuichi Miyazaki, Youichirou Oohashi
