## Abstract

An electronic element includes a substrate, and a transparent conductive layer. The substrate includes a surface. The transparent conductive layer is formed on a surface of the substrate. The transparent conductive layer includes at least one carbon nanotube layer. Carbon nanotubes in the carbon nanotube layer are adhered together by the van der Waals attractive force therebetween.

## Claims
