In a conductive sheet constituting a touch panel for use in a display device, it is possible to improve the transmittance of electrodes having meshes, to improve sensitivity of touch detection, and to suppress the occurrence of moire. A conductive sheet has an underlying first electrode and an overlying second electrode with a second sheet body as an insulating layer sandwiched therebetween. The first electrode and the second electrode respectively include a plurality of first cells and a plurality of second cells which are formed in a diamond shape by making thin wires and formed with metal wires intersect each other. The average cell pitch of the second cells is set to an integer multiple equal to or greater than two times and equal to or less than eight times the average cell pitch of the first cell.

Conductive sheet, capacitive touch panel, and display device

An object of the invention is to provide a conductive film that can prevent an operation error caused by ion migration and is suitable for, for example, a projected capacitive touch panel, a method for manufacturing the conductive film, and a touch panel using the conductive film. In the conductive film, a resin layer is laminated on a surface of a substrate. A mesh-shaped groove portion is formed in a surface of the resin layer. A thin metal wire is provided in the groove portion to form an electrode pattern. When a value indicating ion migration characteristics of the electrode pattern in a longitudinal direction is ML and a value indicating ion migration characteristics of the electrode pattern in a lateral direction is MS, a migration ratio obtained by dividing the larger of the two values ML and MS by the smaller value is in the range of 1.0 to 1.4.

Conductive film, conductive film manufacturing method, and touch panel

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.
