    Abstract: In a conductive sheet having two metal meshes disposed to overlap each other, it is possible to increase the transmittance of the conductive sheet, to suppress moire generated between two electrodes, and to increase touch detection accuracy in a case where the conductive sheet is used in a touch panel. In a conductive sheet, a lower electrode and an upper electrode are disposed with a second sheet body (insulating layer) sandwiched therebetween. For example, the lower electrode has a mesh pattern formed by a plurality of linked second cells, and the upper electrode has a random mesh pattern including a plurality of first cells having different shapes. An average cell pitch Ps of the first cells is set to be greater than once and equal to or less than eight times an average cell pitch Pd of the second cells.
