The present invention relates to a touch sensor having enhanced durability and optical characteristics and a method of manufacturing the same. The method includes: supplying a touch sensor to an annealing chamber, the touch sensor including a base film and a touch sensor layer formed on the base film; and performing an annealing process on the touch sensor in the annealing chamber, wherein a thickness of a transparent electrode unit constituting the touch sensor layer ranges from about 35 nm to about 150 nm. According to the present invention, by optimizing the thickness and annealing conditions of the transparent electrode unit that affect the durability and optical characteristics of the touch sensor, flexibility and durability of the touch sensor can be simultaneously enhanced while minimizing degradation of the optical characteristics of the touch sensor.
A touch sensor having enhanced durability and optical characteristics, comprising a transparent electrode unit constituting a touch sensor layer, which has an elongation of about 1.6% to about 7.0% and a base film having the thickness in a range of about 5 μm to about 200 μm formed on the touch sensor layer
