PROBLEM TO BE SOLVED: To provide a touch panel that is formed of a transparent resin base material, suppresses warpage that occurs due to a change in temperature and humidity in an environment, prevents an effect on a liquid crystal display body arranged below the panel, and further suppresses incorrect operation.SOLUTION: A sensor base material 2 has a plurality of signal detection electrode lines 2b formed on one face of a transparent resin base material 2a, and has a transparent resin layer 1 provided on both faces thereof. The transparent resin layers 1 are made of the same material or materials having a difference in the coefficient of thermal expansion of within 10%, and the thickness of the transparent resin layer 1 is in a range of 0.1 mm to 5 mm.SELECTED DRAWING: Figure 1 |
