A projected capacitive touch panel has an upper substrate and a lower substrate. The upper substrate has multiple upper conducting layers, and each upper conducting layer has multiple upper sensor units serially connected. The upper substrate further has an insulating ink layer being non-transparent, formed on a perimeter of the bottom of the upper substrate, covering an edge of the upper sensor unit located on one end of each upper conducting layer in a direction, overlapping with the lower ports and the lower wires of the lower substrate, and having multiple reserved slots, each formed through a portion of the insulating ink layer overlapping with a corresponding upper sensor unit, and multiple conductors, each mounted in a corresponding reserved slot. The insulating ink layer masks the wires and ports on the lower and upper substrates, thereby eliminating the use of a masking cover, saving the cost and thinning the product.
