High strength touch panel and method of manufacturing the same

A method for producing resistance film type touch panels, whereby an upper electrode sheet (1) having a plurality of upper electrodes (111) on one face of a flexible transparent film (9) and a hard coat layer (12) on an other face of the film, and a lower electrode sheet (2) having a plurality of lower electrodes (121) confronting the plurality of upper electrodes on one face of a glass substrate (10) are disposed to face each other over a distance maintained by spacers (13) between the upper electrodes and the lower electrodes confronting the upper electrodes with respective peripheries of the upper electrodes and the lower electrodes confronting the upper electrodes being bonded by an adhesive layer (3), and then divided into individual touch panels,

• said method comprising:
• bonding the upper electrode sheet having the plurality of upper electrodes and the lower electrode sheet having the plurality of lower electrodes by means of the adhesive layer;
• thereafter projecting a laser light beam (4) from a side of the upper electrode sheet thereby cutting the upper electrode sheet for each of the upper electrodes, with notching from a side of the lower electrode sheet with use of a cutter (6) thereby forming first grooves (7) in the glass substrate of the lower electrode sheet;
• and
• thereafter dividing the glass substrate along the first grooves to obtain individual high-strength touch panels (8).
