Document Type and Number:

WIPO Patent Application WO/2021/235145

Kind Code:

A1

Abstract:

[Problem] To provide a conductive sheet and a touch sensor which have improved visibility and suppressed glare when a mesh shape is set to be an irregular pattern. [Solution] This conductive sheet 10 comprises a transparent base material 11 and a plurality of thin metal wires 12 formed in a mesh shape on one surface of the transparent base material 11. The plurality of thin metal wires 12 include a hexagonal shape and six coupling lines formed in a virtual pattern Xa and an inverted virtual pattern Xb. The virtual pattern Xa and the inverted virtual pattern Xb that is a left-right inversion of Xa, in which the hexagon shape and the six coupling lines are formed by the plurality of thin metal wires 12, are spread out such that each intersection disposed at each side of the adjacent virtual pattern Xa or inverted virtual pattern Xb overlap, and such that an opening region R formed by the plurality of thin metal wires 12 is arranged in an aperiodic manner.
