Abstract

An optically transparent conductive material including an optically transparent support; and a pattern of metal thin wires of repeated unit figures formed on the optically transparent support, wherein the unit figure is a combination of a main cell and a satellite cell, the number of cells sharing a side and/or a vertex with and adjacent to the main cell is larger than the number of cells sharing a side and/or a vertex with and adjacent to the satellite cell, and the longest distance between two arbitrarily selected points on the metal thin wires forming the main cell is longer than the width of the main cell in a direction perpendicular to the direction between the two points.

First claim

1 . An optically transparent conductive material, comprising:
an optically transparent support; and a pattern of metal thin wires of repeated unit figures formed on the optically transparent support, wherein each of the unit figures is a combination of a main cell and a satellite cell, the number of cells sharing a side and/or a vertex with and adjacent to the main cell is larger than the number of cells sharing a side and/or a vertex with and adjacent to the satellite cell, and the longest distance between two arbitrarily selected points on the metal thin wires forming the main cell is longer than the width of the main cell in a direction perpendicular to the direction between the two points.

2 . The optically transparent conductive material according to claim 1 ,
wherein the main cell and the satellite cell are each a closed figure that begins and ends at the same point, the point being one arbitrarily selected point on a side forming the figure, and the main cell and the satellite cell are each a figure that is no longer a closed figure once the figure is further divided.

3 . The optically transparent conductive material according to claim 1 ,
wherein the cells sharing a side and/or a vertex with and adjacent to the main cell and the cells sharing a side and/or a vertex with and adjacent to the satellite cell are each a closed figure that begins and ends at the same point, the point being one arbitrarily selected point on a side forming the figure, and these cells are each a figure that is no longer a closed figure once the figure is divided.

4 . The optically transparent conductive material according to claim 1 ,
wherein the pattern of metal thin wires comprises a region as a sensor part, the sensor part is formed of linear electrodes aligned in one direction, each linear electrode being a strip-like conductive region extending in a direction perpendicular to the one direction, and the unit figures in the pattern of metal thin wires forming the sensor part are repeatedly aligned in the direction in which the linear electrodes extend and the direction in which the linear electrodes are aligned.

5 . The optically transparent conductive material according to claim 4 ,
wherein at least three unit figures are repeatedly aligned in the direction in which the linear electrodes of the sensor part are aligned, at a narrowest portion of the strip-like conductive region formed of the linear electrodes in the direction in which the linear electrodes of the sensor part are aligned.

6 . The optically transparent conductive material according to claim 1 ,
wherein the main cell has a rhombus shape.
