A single-layer projected capacitive touch panel has a glass cover, a touch sensing circuit layer, an insulating ink layer, a conductive wire layer, an insulator layer, a conductive glue layer and a flexible printed circuit (FPC) board. The touch sensing circuit layer, the insulating ink layer, the conductive wire layer, the insulator layer and the conductive glue layer are mounted on a circuit surface of the glass cover in sequence. The insulating ink layer covers the touch sensing circuit layer and has multiple through slots. Each through slot is filled with an electric conductor. The FPC is fastened on the conductive wire layer by a conductive glue layer. Therefore, the touch panel of the present invention is thinner, provides better penetrability and costs less than conventional projected capacitive touch panels.
