Abstract
Provided is an optically transparent conductive material which does not cause moire or grain even when placed over a liquid crystal display, that is, has a favorably low visibility (moire and grain are less recognizable), and has a high reliability. The optically transparent conductive material has, on an optically transparent base material, an optically transparent conductive layer having sensor parts and dummy parts, the sensor parts and/or the dummy parts being formed of a metal mesh pattern consisting of Voronoi edges formed based on a plurality of generators arranged in a plane tiled using polygons longer in the first direction than in the second direction, the mesh pattern being characterized in that each polygon has only one generator arranged in the polygon and that the generator is at an arbitrary position within a reduced polygon formed by connecting points at 90% or less of the direct distance from the center of gravity of the polygon to each vertex of the polygon.
