Document Type and Number:
WIPO Patent Application WO/2022/071063
Kind Code:
A1
Abstract:
[Problem] To provide a conductive sheet, touch sensor and touch sensor manufacturing method in which generation of the appearance of moire effect and patterns is suppressed via a mesh shape having a reduced design load. [Solution] A conductive sheet 10 comprises: a transparent base material 11; a plurality of first fine metal wires 20 formed on a first surface 11a of the transparent base material 11; and a plurality of second fine metal wires formed on a second surface 11b of the transparent base material 11. The first fine metal wires 20 are disposed side by side in the row direction and the column direction such that the vertices of first quadrangles Sa overlap. Each of the first quadrangles Sa have one side missing. The second fine metal wires 30 are disposed side by side in the row direction and the column direction such that the vertices of second quadrangles Sb overlap. Each of the second quadrangles Sb have one side missing. The second quadrangles Sb are disposed at positions shifted in the column direction from the first quadrangles Sa by half the distance of a diagonal line in the column direction of the first quadrangles Sa. The second fine metal wires 30 do not overlap wires of the first fine metal wires 20 in the same direction.
