1. A method for manufacturing a transparent circuit board, comprising:
providing a composite substrate, the composite substrate comprising a conductive layer and a transparent insulating layer on the conductive layer;
forming a wiring groove on the transparent insulating layer by laser ablation, and forming a carbon black layer on an inner wall of the wiring groove, wherein the wiring groove penetrates the transparent insulating layer, the wiring groove extends toward the conductive layer to pass through a part of the conductive layer;
forming a conductive wiring corresponding to the wiring groove, the conductive wiring fully filling the wiring groove;
performing a black oxide treatment on a surface of the conductive wiring facing away from the conductive layer to form a blackened layer;
pressing a transparent cover film on a side of the transparent insulating layer facing away from the conductive layer; and
removing the conductive layer.
