Transparent conductive element, information input apparatus, and display apparatus

摘要

A transparent conductive element is provided and includes a conductive layer having a first surface and a second surface and a medium layer formed on at least one of the first surface and the second surface. In the transparent conductive element, at least one of the first surface and the second surface is a wave surface with a wavelength shorter than or equal to that of visible light; the ratio (Am/λm) of a mean peak-to-peak amplitude Am to a mean wavelength λm of the wave surface is 1.8 or less. The mean thickness Dm of the conductive layer is larger than the mean peak-to-peak amplitude Am of the wave surface.
