Abstract

An object of the present invention is to provide a transparent conductive material that can prevent cracks or abrasions on the conductive layer due to repeated use, while maintaining a high conductivity. The transparent conductive material of the present invention has a conductive layer 4 containing a binder 3 and conductive particles 2 held with the binder. In the transparent conductive material, at least a portion of some of the conductive particles 2 is exposed on an outermost surface of the conductive layer, and a fluorine compound is unevenly present on an exposed surface of the conductive particles exposed on the outermost surface of the conductive layer.

Description

technical field

[0001] The present invention relates to transparent conductors. Background technique

[0002] A panel switch such as a resistive film touch panel (hereinafter referred to as a touch panel) is generally composed of a pair of transparent electrodes facing each other and a spacer sandwiched between the pair of transparent electrodes. If there is a transparent electrode, then the transparent electrode will be in contact with another transparent electrode and energized, thereby detecting the position of its contact point. A transparent conductor is used as the transparent electrode, and the transparent conductor is formed by using a conductive powder and a resin as a conductive layer (see JP-A-11-227740).

[0003] When this transparent conductor is used for a touch panel, opposing transparent conductors come into contact with each other, and friction occurs between the transparent conductors.

[0004] For this reason, if the touch panel is used repeatedly, crack...
