PURPOSE: A touch panel is provided to reduce the production cost and to enhance the productivity by enabling the parts wanted to exchange to easily exchange the defect part. CONSTITUTION: The touch panel comprises an upper substrate(11) equipped with an upper transparent conductive film(12), a lower substrate(15) equipped with a lower transparent conductive film(14), a plurality of dot spacers(16) formed between the upper and lower transparent film in order to prevent the contact between the upper and lower transparent film without outer pressure, and an adhesive layer adhering the upper and lower transparent film. The adhesive layer adhering the upper and lower transparent film uses a formed both-faces adhesive tape. Both faces of supporter are coated with the adhesive agent and the under coating connecting the supporter with the adhesives is inserted between the supporter and the adhesives. The materials of supporter are polyurethane and polyethylene. The formed both-faces adhesive tape has a thickness of 50-150 micrometers, the diameter of foamed particle is 20-70micrometers and the materials of foam is expanded by 2 to 5times at 150 deg.C. |
