The capacitance touch screen is characterized in that the ITO electrodes are etched into a plurality of X electrodes along the X-axis direction and a plurality of Y electrodes along the Y-axis direction, wherein the X electrodes are kept continuous on the X-axis direction; the Y electrodes are etched and broken at the crossed area of the X electrodes and the Y electrodes; a layer of SiO2 is plated on an X electrode layer in the crossed area so as to determine that the X electrodes are insulated from the Y electrodes; and a layer of molybdenum-aluminum-molybdenum is coated on the layer of SiO2, so that the Y electrodes are conducted. A silver paste circuit layer is paved on the edge of the glass substrate; and the silver paste circuit layer is electrically connected with the ITO electrodes. Compared with a traditional touch screen with multi-layer structures, as the ITO electrodes on the X direction and the Y direction are arranged on the same layer, the technological process is simplified and the touch screen is thinner with a low cost.
