The invention discloses a method for manufacturing a touch screen, which comprises a screen printing step; a combination step: namely covering one side of a non-base material optical adhesive tape on a support plate, attaching the support plate and the non-base material optical adhesive tape by using an automatic laminator; cutting off a lead bending gap on the support plate attached with the optical adhesive tape corresponding to a pressing position where the lead is inserted by using a laser; aligning a positioning hole on one side of a lower line ITO film with the positioning hole on corresponding side of the support plate, then attaching a lower surface of the lower line ITO film and the support plate by using a plastic package machine; attaching an upper line ITO film and the lower line ITO film through individual positioning hole of the upper line ITO film and the lower ITO film, and hot-pressing and shaping; a cut off step and a steps for inserting the lead. The touch screen manufactured by the inventive embodiment is thin and extrusion resistant, and has high bending degree in the lead.
