The invention provides an outgoing line via overlap structure of a capacitive touch screen. A touch function area of the capacitive touch screen is in a single-layer structure. Vias of outgoing lines from an induction layer pattern are overlapped by the aid of an insulating layer and leads. Blank areas are preserved on the insulating layer at the overlap positions of the outgoing lines of the induction layer pattern and the leads. One blank area corresponds to the overlap of one outgoing line of the induction layer pattern and one lead. The leads and the outgoing lines of the induction layer pattern are disposed on two sides of the insulating layer respectively and are communicated by overlapping by the aid of the blank areas preserved on the insulating layer.
