The invention discloses a bridging and wire-leading sensor of a monolayer multi-point touch screen and a forming process thereof. The forming process is characterized by comprising the following steps: firstly, providing an insulating and transparent substrate, and etching one surface of the substrate into an induction electrode and an indium tin oxide (ITO) leading wire which extends out, wherein contacting points and bridging points for bridging connection are arranged at the tail end of the leading wire, then, keeping on forming a transparent insulating layer on the surface of the substrate, wherein the insulating layer covers all bridging points in the plane and presetting through holes at positions of the bridging points, and at last, forming a bridging layer on the substrate, the insulating layer of which is processed, wherein the bridging layer is positioned on the surface of the insulating layer or comprises the surface of the substrate, the bridging layer is communicated with the bridging points through the through holes, and the bridging and wire-leading sensor is got. Due to the fact that bridging wires exist, the contacting points of the monolayer multi-point touch screen are distributed evenly, the phenomena that the contacting points are blocked and crossed by the leading wire are avoided, the widths of the contacting points and wire distance are enlarged, binding difficulty between the contacting points and flexible printed circuit (FPC) is reduced, and yield is increased.
