Claim:
1. A conductive sheet comprising: a substrate; a first conductive portion formed on one main surface of the substrate and made up from a plurality of thin metal wires that have a width being greater than or equal to 0.1 μm and less than or equal to 15 μm and are formed from a non-transparent material; a first protective layer disposed on the one main surface in covering relation to the first conductive portion; a second conductive portion formed on another main surface of the substrate and made up from a plurality of thin metal wires that have a width being greater than or equal to 0.1 μm and less than or equal to 15 μm and are formed from a non-transparent material; a second protective layer disposed on the other main surface in covering relation to the second conductive portion; a first adhesive layer disposed between the one main surface and the first protective layer; and a second adhesive layer disposed between the another main surface and the second protective layer, wherein at least one of a relative index of refraction of the substrate with respect to the first protective layer and a relative index of refraction of the substrate with respect to the second protective layer is 0.86 to 1.15, wherein the first conductive portion comprises a mesh pattern in which different mesh shapes are arranged randomly in plan view, wherein each of the mesh shapes is polygonal, wherein a percentage of polygons having a number of vertices, an occurrence frequency of which is highest in a histogram of the number of vertices in the mesh shapes, is 40% to 70%.
