Claim:
1. A touchscreen sensor comprising: a transparent base material; a first transparent electrode pattern, a first index-matching layer and a first adhesive layer disposed in this order at one side of the transparent base material, the first index-matching layer being provided on the first transparent electrode pattern, the first adhesive layer being provided on the first index-matching layer; and a second transparent electrode pattern, a second index-matching layer and a second adhesive layer disposed in this order at another side of the transparent base material, the second index-matching layer being provided on the second transparent electrode pattern, the second adhesive layer being provided on the second index-matching layer, the first index-matching layer having a refractive index greater than a refractive index of the first adhesive layer, the second index-matching layer having a refractive index greater than a refractive index of the second adhesive layer, each of the first index-matching layer and the second index-matching layer having a thickness of 85 nm to 120 nm.
