Abstract
A transparent circuit board includes a conductive wiring, a transparent insulating layer, and a cover film stacked on the transparent insulating layer. The conductive wiring penetrates the transparent insulating layer along the stacking direction, and is at least partially embedded in the conductive wiring. A blackened layer is formed on a surface of the conductive wiring combined with the cover film, a carbon black layer is formed on a surface of the conductive wiring without the blackened layer, thereby improving a light transmittance of the transparent circuit board.
